And while we do think understanding these components of stopping power is important, it is all worthless if you can’t put the right bullet where it needs to go. Copyright Ron Spomer Outdoors © document.write(new Date().getFullYear()) By Ron Spomer. For a bullet to quickly kill an animal, it must reach the vital organs. fans don’t jump in here and spoil the argument or I’ll let the 300 RUM lovers counter. The majority of bullet weights used for the 7mm rem mag rounds for hunting purposes fall between 150 and 180gr though there are outliers of lighter and heavier bullets. The exterior and terminal ballistics of the two are virtually identical, but looking at the ammunition options, you’ll find there are many more choices for the WSM. At the 200 yard mark, all ten of these rounds are clustered very tightly with a difference of only .7” between the flattest and steepest round. The second metric that we will use to get an idea of how these two cartridges compare in potential penetration is the momentum of the bullets. If you’re interested in the averages, the 7mm Rem Mag has an average BC of .56 while the .300 Win Mag has an average BC of .553. When thinking about how much penetration is necessary, you also have to think about the type of game you are hunting. You can cherry pick a round from each and see quite a bit of difference as we did earlier, but there are a lot that carries very similar energies, and we saw that as they travel downrange they even out even more. Some of our reasons for selecting this round is the terminal ballistics and the stopping power. Just between cartridges, we don’t think there is enough of a difference to choose one over the other based on price. Because a lot of the discussion is going to revolve around these ten rounds, and because we are very aware of the possible issues when trying to use a small sample size to extrapolate performance to a much larger field, we have compiled extra rounds for each cartridge. You can definitely save a few cents per round by looking into handloading for both of these cartridges. It was released to the civilian market in 1962 and quickly gained popularity in the hunting world. Comparing the .270 with the 7mm Remington magnum is like comparing grits and white cornmeal. We can do the same exercise, but instead look how the weight of the bullet affects the SD. And for hunting purposes, we are not sure that an extra .300 ft.lb of force is going to make much of a difference. We have to cut it off somewhere. November 25, 2019. This cartridge was able to match and even excel in several ballistic categories compared to the .30-06, one of the most popular long range, big game cartridges at the time, but the 7mm rem came with much more tolerable recoil when compared to other magnum cartridges on the market. Given that the cartridge is still around tells you that it is able to bring down large game efficiently. After we have examined these sections, we should have a much clearer understanding of where these cartridges excel and where they fall short and will let us begin teasing apart applications one cartridge might be favored over the other. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Both cartridges fit through standard length actions, both maximize performance in 26-inch barrels but do fine in more convenient 24-inch tubes. For the sake of clarity and brevity, we decided on only five selections each. We have listed the average cutoff for supersonic flight in the table below. Sight Height (in) Must be a number greater than 0. BCs are also important in the trajectories of bullets. THE BEST GUN DEALS AND HANDPICKED GEAR RECOMMENDATIONS, Subscribe to our Newsletter and we send you the best deals right into your inbox. Zero Range (yd) Must be a number greater than 0. The .100″ bullet is going to have a larger SD than the .200″ bullet and theoretically, deeper penetration. With practice, either one can easily become your go to round. What is interesting is that as these rounds move downrange, the gap between the two cartridges begins to close. The 300 WM kicks slightly more. If we look at some of the ballistics data such as the ballistic coefficients and the trajectories, there is not a whole lot of difference between the two cartridges in either category. It has one the best muzzle velocities and BCs of all the rounds we looked at so you have excellent downrange ballistics, including a flat trajectory. Base: 12.0 mm From the first look, there are no significant differences between 7mm Remington Magnum and .30-06 Springfield when it comes to profile. And if you need some extra power at short range the differences are nowhere enough to make you decide against the .300 Win Mag. Still, it is accepted that 1,000ft.lb of energy is a good mark for deer while 1,500ft.lb is more suitable for elk. In 2004 I took my 99 .270 WSM and a light .375 H&H. That’s a difference of 478ft.lb. We have compiled the G1(for comparison of all bullet types) ballistic coefficients for each of the ten rounds and listed them here (Graph 3). Hunting . Best 9mm Ammo 2019 [Self-Defense & Target], 6.5 Creedmoor vs .243 Win – Cartridge Comparison, Best .40 S&W Ammo: Self Defense & Target Practice. Caliber: Bullet Weight: Overall Cartridge Length: Muzzle Velocity: Trajectory at 300 yds(100yds zero) Muzzle Energy(Ft. Unfortunately, there is no single measurement that is going to convey to us a cartridge’s stopping power, but there are several factors that influence stopping power such as bullet energy, penetration, and bullet expansion. Parent Case: .375 H&H Magnum 2. We put 3 popular cartridges to a head-to-head-to-head test. 7mm Remington Magnum (7.2x64mm) 1. The 300 WSM will have more recoil than you presently have, but put on a Vais muzzle brake and recoil will … In fact, we don’t think there is a big enough difference in these categories to make you lean one way or the other regarding accuracy from the data we have looked at here. When you have two cartridges that overlap in a lot of shooting situations each category deserves some consideration. UMC Handgun; Hog Hammer Handgun; HTP Copper Handgun; Subsonic; Performance WheelGun; High Terminal Performance (HTP) Ultimate Defense Compact Handgun Loads Tomahawks Are Back: These American Relics Have Seen a Resurgence in Military and Survival Situations. Bullet: 7.2mm 4. Both of these magnum rounds have been in circulation for just about the same amount of time. Complete 7mm Remington Magnum Winchester ammunition ballistics Chart. Ballistics Comparison for 270 Regardless of where your allegiances are situated in this topic, hopefully you are coming into this with an open mind, because both of these magnum rounds are tremendous cartridges and their popularity and longevity in such a cutthroat field speaks in volumes to their performance. Again, this is all relative and depends on who is holding the gun. By the time they reach the 500-yard mark, that difference is nearly cut in half to 224.4ft.lb of difference. Cartridge Type: Rifle Height: 2.1" Width: 0.535" Average FPS: 3134 Average Energy: 3314 Average Gr: 152 Recoil: 2.06 Power Rank: 4.76 of 20 The 7mm Winchester Short Magnum (WSM) was designed in 2001 by Winchester Repeating Arms Company and Browning Arms Company. You really are comparing apples and oranges. Compare all 7mm Remington Magnum ammunition manufacturers on one easy to read chart. The 7mm Rem Mag has become over recent years, one of the most popular magnum rounds on the market for hunting purposes. While the .300 Win Mag has a higher case capacity and can take higher pressures, it also must send heavier grain bullets down range while maintaining necessary terminal ballistics. The higher the BC, the better the bullet can cut through the wind, meaning it resists drag and wind drift much more efficiently than a bullet with a lower BC. Penetration is another component to a bullet’s stopping power that we want to address in this article. Rifling Twist: 1:9 to 1:10 3. Meaning, how well can the object, a bullet in this case, overcome resistance and keep moving forward. Personally I MUCH favor the 7mm Mag over the 300 WSM. The .300 WM rounds are generating more momentum from the muzzle out to 500 yards. The fact that both are still used and still a topic of debate should give you an idea that both can be highly effective rounds in the right hands and the right situations. In the simplest explanation possible, the ballistic coefficient gives you an idea of how well a bullet is streamlined and how well it can overcome air resistance. While we will examine it as a standalone performance category, velocity has its hand in just about all other performance specs of a cartridge. As the species increase in size so does the amount of energy. It is also available in a wide array of bullet styles which gives it a lot of versatility. Instead, your advantage is going to be achieved by selecting from individual rounds and both the .300 WM and the 7mm RM have rounds with phenomenal trajectories. More than enough to have a good feel for their strengths and their weaknesses. As we move out the 300-yard mark, there is a little more spread between the rounds but still no clear cut advantage for one cartridge over the other. In our opinion, you can become accustomed to any recoil within reason it still stands that certain amounts can cause you to flinch or close your eyes before a shot. Rifling Twist: 1:10 3. 7mm Magnum Showdown: 7mm Rem. INDEX/ WT BALLISTIC EDI NO. In this case, the 7mm Rem Mag shows slightly less bullet drop than the .300 Win Mag round and even at their most distinguishable range, we are only looking at around 5” difference. At the 300 yard mark, we are looking at insignificant differences between the two cartridges. Remington released their 7mm and .300 short action ultra magnums in the same year and a year later, Winchester released the 7mm and .270 WSM cartridges. That introduction was, I’m guessing, retaliation against Remington’s 1962 release of its equally famous 7mm Remington Magnum. Both are excellent cartridges. There are several factors that influence the amount of penetration that is going to occur, other than the type of animal. You will find these tables at the end of each section throughout the article. It also means that if you look around at handloading website, you are going to see numbers that sometimes vastly outperform the rounds we will be looking at in this article. We know from basic physics that if the cartridge can be fitted with larger and heavier bullets and sent downrange at increased speeds (more powder) than they should carry extra force with them. While hand loading and the art of balancing the various components that go into a cartridge is a topic worth discussing, it is beyond the scope of this article. The belted cartridge is not going to be quite as accurate as a rimmed cartridge by design. Best Concealed Carry Insurance [Comparison Chart], If you’re looking at a cartridge comparison, you are going to end up looking at the ballistic categories. Both of these combined, barring bullet design, indicate that the .300 Win Mag should have better penetration potential. 300 Remington Ultra Magnum Load Data; 7.62x51mm NATO Load Data; 8x57mm JS Mauser Load Data; 8mm-06 Load Data; 325 Winchester Short Magnum (WSM) Load Data; 8mm Remington Magnum Load Data ; 338 Federal Load Data; 338-06 A-Square Load Data; 338 Winchester Magnum Load Data; 330 Dakota Load Data; 340 Weatherby Magnum Load Data; 338 Remington Ultra Magnum Load Data; 338 Lapua Magnum … Now, you 300 Weatherby Mag. It was by no means the first cartridge designed in the magnum category as the popular 7mm Remington Magnum was released the year prior, but the .300 WM seemed to come out at the right time. It is also important to keep the sectional density in mind when looking at momentum. And, this is of course omitting the type of bullet that is being fired which in the field, is going to have to be taken into consideration. Both are loaded with a wide variety of some of the the best bullets in the world and both are widely distributed and easily found. A mature bull moose is going to require more penetration than a whitetail deer. From what we are looking at from these factory loads, velocity is definitely a wash between the 7mm Rem Mag vs .300 Win Mag, but that might not be the case when we bring in more data. These results shouldn’t be too surprising. With that type of similarity, it’s hard to even say it’s an advantage. This speed along with the sectional density is going to be more than enough to penetrate to and through vital organs of big bull elk and moose at long ranges. When we look at this graph, we see a clear and distinct difference in recoil energies produced from these two cartridges. At least some companies like Remington and SAKO put the 7mm Rem Mag in rifles with 3.6" magazines so it can shoot low drag bullets. These are factory loads, and the performance data we are looking at comes from the manufacturer’s website and well trusted and accurate ballistic performance calculators. While this cartridge has been and is still used in sharp shooting corners of the military, the majority of its action is found in the hunting world. This is common, and most are not even aware that this occurs and when it does, it is usually not a noticeable difference. G1 Ballistic Coefficient Must be between 0.001 and 1.0. We have also added an additional 1,000 yard marker for those who like to push their limits. The best method of doing this is through hundreds of rounds through several days of shooting and measuring groupings. With a degree in Microbiology and several years of doctoral work manipulating bacterial genes, he attempts to merge the rational and unbiased thinking of scientific research with the passions of hunting and fishing. Regardless, if I had to pick just one of these for all-round hunting, it would be the 7mm Rem. We've got you covered. In this section, we will take a look at several ballistic categories including the velocity, the ballistic coefficient, as well as the short and long range trajectory of the 7mm Rem Mag vs .300 Win Mag. BONUS OFFER: Get your 500 Page Ammo Comparison Handbook (worth $43) for FREE right into your inbox. With these two cartridges, we see fairly similar limits for supersonic flight though the 7mm RM rounds have, on average, 36 more yards of supersonic speed. It is important to remember when looking at these averages, that they are just averages and you’re not shooting averages out the barrel. A small lack of force can be made up for with an accurate shot in the vitals. We have compiled the velocities of the ten selected rounds from the manufacturer’s websites and have listed them here. As with the velocity, we see a lot of variation in BCs throughout all ten selected rounds and within each cartridge class. The .300 WSM was the first of Winchesters short magnum family, released in 2001. And when we say highest or lowest performing, we mean that in regards to only the momentum numbers. On average, the 7mm Rem Mag rounds have a SD of .279 while the .300 Win Mag rounds have an average SD of .289, a hundredth of a difference. Latest. Though the averages give a slight advantage to the 7mm Rem Mag in flat trajectories, especially as it moves out to the 600 and 700 yards range, the two top performing rounds at each yardage marker was a 7mm RM and a .300 WM. Mag. You might see slower velocities as well as changes in bullet energy and trajectory. With two bullets, each with a .300” diameter with one weighing 100gr and the second 150gr, the 150gr is going to have a higher sectional density and deeper penetration. Of course, it might also tell us that both are more than capable of doing the same thing efficiently and effectively. Velocity is also a key component in a bullet’s ability to expand, but for now, we are just going to stick with comparing the energies of the rounds involved. The averages of the rounds for each cartridge have a difference of less than .4”. The velocity is an interesting and critical performance spec for any cartridge comparison. For penetration, we will actually look at two different metrics, the sectional density and the bullet momentum. Instead, we want to present the numbers and discuss any strengths and weakness of both cartridges. We are looking at the ft/s of each bullet as it moves from the muzzle out to 500 yards (Graph 2). Before we wrap up this article, we want to take the ten rounds we have been looking at and pick a couple that we think fits certain applications well. For long range precision shooting, both of these rounds have options to get the job done. We have kept some of these variables as constants to better compare the two cartridges. We’ll pretend both rifles weigh 8-pounds as shot. Below you will find the velocity averages for the two cartridges. We do see that the Barnes .300 WM round is a big boost to the averages and without it, the average performance between these cartridges would be much similar. Both of these cartridges sports rounds with ballistic coefficients well over .45 and each have rounds with BCs above the .6 mark. We have graphed the bullet momentum of our ten rounds and graphed them below (Graph 9). We also do not see any trend towards one cartridge having a flatter trajectory than the other. Each cartridge is today the most popular magnum in its caliber, raising the question: Which is the best all round hunting cartridge? As the names imply, the.300 Win Mag takes a 30-cal (.308″) bullet, while the 7mm Rem Mag takes a smaller caliber (.284″) bullet. If you are planning to shoot factory ammunition only, check back here for Part Two of this cartridge comparison blog. The 7mm Rem Mag, on the other hand, is using lighter bullets. 3.89 lbs. Both are very capable and popular cartridges and both pack a good punch. The sectional density correlates with the amount of penetration a bullet will have on the target, and since we are not looking at bullet types and designs in this article, we think the SD is a good means of comparison for two cartridges. And recoil does play a role in choosing a cartridge, especially if you are dealing with a decision on cartridges that can be used for similar applications. As we start top close out this comparison, let’s try to take the results we have found and start teasing apart certain applications of these cartridges might be better suited or maybe applications where you can’t go wrong with either. Bei der 7mm Rem Mag sollte man bedenken, daß sie einen etwas längeren Drall hat als die 7x64. When we add in more rounds, we are still seeing the same trends as before. And you can’t discount the role recoil can play in accuracy. Unlike the last couple of performance categories we have looked at, here we see a distinct difference between the two cartridges more so than just between different rounds. As long as you keep those variables constant from round to round, the trends we see are going to remain the same. Of these, 140 grain, 150 grain, 160 grain, and 175 grain loads are by far the most common. Both have been popular from their inceptions. The following ammunition cartridge ballistics information and chart can be used to approximately compare .300 WSM Winchester Short Magnum vs 7mm-08 Remington ammo rounds. Deciding which you prefer comes down to levels of recoil, downrange energy, bullet drop and bullet drift, none of which are significant unless you plan to be throwing at targets beyond 500 yards. We think the 168gr bullet is a great weight for hunting purposes as it has a manageable recoil. Tomahawks Are Back: These American Relics Have Seen a Resurgence in Military and Survival Situations . 3.5 lbs. This is because the force behind the bullet is localized to a smaller area and can drive the bullet deeper. The higher the sectional density, the less resistance the bullet encounters because of the smaller area that is interacting with the target. October 2, 2019. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufact The 300 win mag … For others, the trend of the 7mm RM losing altitude at a slower rate than the .300 Win Mag as you increase the distance is very important. A war’s been raging since 1963. This transfer is also affected by how the bullet reacts on impact, such as how the bullet expands. In this next section, we are going to look at several sub-categories of stopping power. This is more than enough velocity to get proper terminal ballistics for these rounds but keep in mind some of these are not intended for hunting purposes. We kept both of these cartridges with being fired with a 9lb firearm, and the powder loads were selected from load data. For us and the majority of hunters we know, putting down an animal quickly and humanely is of utmost importance. This difference between the two leads us to rounds that have very similar SDs. Contrary to popular belief, the heavier bullet does not drift less in the wind. Lbs.) Given that the mass and velocity make up bullet momentum and since there was very little difference in velocity between the cartridges and the .300 WM rounds have heavier bullets, it makes sense that they generate more momentum. The old long through is just fine for me. Most brands offer 170 to 175-grain options in 7mm RM. From the muzzle out to 300 yards, all of the .300 Win Mag rounds show higher bullet energy than the 7mm Rem Mag rounds. Like the smaller sample set and like the averages we saw when examining the short range trajectory, there is not a whole lot of difference between these cartridges. And like we have mentioned before, using a proper bullet and putting it in the right spot can make up for lack of energy. It's because nearly all gun manufacturers keep putting the WSM cartridges in short actions so you can't shoot low drag bullets. The ballistic coefficient is derived from an equation that includes input variables from specific cartridge specifications including bullet dimensions and velocity. For bigger and more dangerous game, you might like the kinetic energy and larger bullets of the .300 Win Mag but as we discussed in the previous sections, we would be comfortable with either cartridge in these hunting scenarios. If we do go by this rule, the 7mm Rem Mag rounds still could be troublesome for some hunters and marksmen though still a good bit lighter than the .300 Win Mag rounds. Die .300 WM hatte ich mal, derzeit nutze ich gerne die mit der 7mm Rem Mag vergleichbaren 7x66 SE. Sniper Country is reader-supported. Size matters, so let’s stick to the two older magnums. And when we say spread out we are still looking at a range of less than 2.5”. With the larger sample size, we see the same trend that we saw above. When a bullet falls below this speed barrier, its slight is less stable than it initially was and environmental factors begin to have more noticeable influence on the round. Violate this principle by, for example, chambering a lightweight, short action rifle for a powerful Magnum cartridge like the .300 WSM and the result will be a dramatic increase in kick. All Rights Reserved, Now, you 300 Weatherby Mag. Environmental Status. Winchester Ballistic Silvertip ammunition provides hunters immediate knockdown and extreme precision. The 7mm Rem Mag is a flat shooting round that is available in a good selection of bullet weights, though maybe not as many as the .300 Win Mag. Both the .300 Win Mag and 7mm Rem Mag have specific rounds that show a much higher velocity and also rounds that fall lower on the graph.
