300 wsm vs 7mm rem mag ballistics chart

By Ron Spomer. Given that the cartridge is still around tells you that it is able to bring down large game efficiently. The 300 win mag … Mag. Closing Comments The 7mm WSM will likely remain popular for many years due to its ability to be housed in short, lightweight rifles. In the grand scheme of things, we don’t know if that is enough to sway you towards one cartridge or the other without taking into consideration other performance specs. When the bullet impacts the target, this kinetic energy is transferred to the surrounding tissue and organs causing massive damage. Here are the relative recoil levels from both 8-pound rifles in the above scenario: Recoil Impulse          Recoil velocity of rife              Free recoil energy, 7mm Rem. The amount of energy that is required to bring down game varies from animal to animal. And when we say highest or lowest performing, we mean that in regards to only the momentum numbers. We have to cut it off somewhere. When we bring in the extra rounds, we still observe the greater kinetic energy with the .300 Win Mag rounds at each yard marker along the bullet’s flight. What is interesting is that as these rounds move downrange, the gap between the two cartridges begins to close. If you are wanting a BC in the .05+ range, there are options for that with both of these cartridges. For penetration, we will actually look at two different metrics, the sectional density and the bullet momentum. Hunting. 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. Given that, I would happily and eagerly hunt anything with either cartridge — even charging brown bears. While the .300 Win Mag overall has higher bullet energy, the differences are not too extreme. This difference between the two leads us to rounds that have very similar SDs. Stopping or knockdown power as some like to call it is going to be more important to those looking to utilize these cartridges for hunting purposes. We’re don’t mean to insult anyone’s intelligence, and we are probably speaking to the choir here, but a bullet’s flight path is not a straight line but rather a parabolic shape. There are 7mm Rm rounds that outperform some .300 Win Mag and vice versa. Just between cartridges, we don’t think there is enough of a difference to choose one over the other based on price. Right from the muzzle, the lowest .300 Win Mag round is carrying 3,474ft.lb of force while the highest 7mm Rem Mag round is carrying 3,303ft.lb of force. The case and overall length of the .300 Win Mag are slightly longer than the 7mm RM, and its overall case capacity has a larger volume. Temperature (°F) Maximum 140°F; Minimum -40°F. We kept both of these cartridges with being fired with a 9lb firearm, and the powder loads were selected from load data. And we are sure its performance also had something to do with its decades of success. Even without the highest performing round, we still see the rounds from each cartridge grouping together pretty tightly. As well as our in-depth look at the 7mm Remmington Magnum. Parent Case: .375 H&H Magnum 2. 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. None of this matters to the elk. Firearm Setup. So, let’s take a look at the recoil energy of the ten rounds now (Graph 1). If you are planning to shoot factory ammunition only, check back here for Part Two of this cartridge comparison blog. Both of these combined, barring bullet design, indicate that the .300 Win Mag should have better penetration potential. Mag. Let’s take a look at the bullet energies (ft.lb) of the ten selected rounds from the muzzle out to 500 yards (Graph 7). That’s a difference of 478ft.lb. The higher the momentum, the more the bullet can penetrate after encountering resistance. 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. In the larger data set, the .300 Win Mag had a .006 advantage over the 7mm RM rounds. Most brands offer 170 to 175-grain options in 7mm RM. Of these, 140 grain, 150 grain, 160 grain, and 175 grain loads are by far the most common. Most brands offer 170 to 175-grain options in 7mm RM. Look on any forum discussing shooting and the ballistics of a certain cartridge, and you are bound to see the topic of trajectories pop up. As an example, let’s take two rounds, both are 100gr, but one has a diameter of .100″ and the second has a diameter of .200″. The cartridge is also able to be to take a variety of bullet weights. With two decades of chasing all manner of upland game, hooved mammals, strutting gobblers, and any small game that can fit in his Dutch oven, he hopes to offer new ideas and viewpoints on hunting and firearm concepts and traditions. It charts everything; drop, time, energy, velocity, range, and does so in 50 yard steps that are easy to understand. 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. 7mm RM Federal Nosler Ballistic Tip Vital-Shok 150gr, 7mm RM Winchester Expedition Big Game Long Range 168gr, 7mm RM Nosler Trophy Grade AccuBond 140gr, 300 WM Federal Trophy Bonded Tip Vital-Shok 180gr, 300 WM Nosler Trophy Grade AccuBond Long Range 190gr, 300 WM Federal MatchKing BTHP Gold Medal 190gr, Nosler Trophy Grade AccuBond Long Range 190gr, Winchester Deer Season Copper Extreme Point 150gr, Winchester Expedition Big Game AccuBond CT 180gr, Winchester Expedition Big Game Long Range 168gr, Barnes VOR-TX TSX Hollow Point Boat Tail 160gr, Winchester Power Max Bonded Protected Hollow Point 150gr, Federal Power-Shok Jacketed Soft Point 150gr, Remington Core-Lokt Pointed Soft Point 175gr, Hornady American Whitetail InterLock SP 139gr, Nosler Custom Ammunition Partition Spitzer 150gr. Mag., the new .28 Nosler, and the over-the-top 7mm RUM—a shoot-off to find the best. 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. WARNING: In factory loaded ammunition, you’ll be hard pressed to find 300 WM ammo with bullets heavier than 180 grains. For the .300 Win Mag, our choice goes to the Nosler Trophy Grade AccuBond Long Range 190gr. By doing this, you as a reader has a better resource and source of knowledge to make your own decision. We are again looking at the bullet drop (inches) of the ten rounds, but now we are following them out to 700 yards with the firearm zeroed in at 200 yards. The .300 Win Mag came into production by Winchester in 1963. 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 … In our opinion, it can’t be denied that this cartridge can fill several hunting needs and is the reason for its continued existence and in our opinion, one of the best magnum rounds of its caliber class. Size matters, so let’s stick to the two older magnums. vs. 7mm Rem. 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 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. 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. We've got you covered. Though the 7mm Rem Mag rounds are a smaller caliber than the .300 Win Mag rounds, they also have lighter bullets. At the 300 yard mark, we are looking at insignificant differences between the two cartridges. Mule Deer Cartridge Showdown: .270 Win. With practice, either one can easily become your go to round. When we add in more rounds, we are still seeing the same trends as before. That is not to say that there aren’t .300 Win Mag options that can give you very similar performances, but most would rather not deal with the increased recoil for dozens of shots within a short time frame. The polymer tip resists deformation, maximizes long-range performance and promotes expansion. This transfer is also affected by how the bullet reacts on impact, such as how the bullet expands. We used a ballistics calculator to generate the recoil energy (ft.lb) generated from firing each of the ten rounds that we have chosen for comparison. Both are chambered in just about every hunting rifle made, including wonderfully affordable models like. and MV, not just weight. All five of the .300 Win Mag rounds produced between 27 and 32ft.lb of energy, between 7 and 14 more ft.lb of recoil energy than the 7mm Rem Mag rounds. We are looking at the bullet drop (inches) from the 50 to 300 yards with the firearm zeroed in at 100 yards. 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. While the three .300 Win Mag rounds maintain their lead; the other two are tightly clustered with several 7mm Rem Mag rounds. 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. We are not here to lobby for one cartridge over the other. Complete 7mm Remington Magnum Winchester ammunition ballistics Chart. For long range precision shooting, both of these rounds have options to get the job done. Both are very capable and popular cartridges and both pack a good punch. fans don’t jump in here and spoil the argument or I’ll let the 300 RUM lovers counter. To engage this 7mm RM vs. 300 WM argument you have to be willing to pick at nits because, bottom line, both cartridges (and many other magnums like them) are winners. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufact Latest. If you need a round that’s going to resist wind deflection and drag, both the 7mm RM and the .300 WM have options to get the job done. In my opinion both the SAUM and WSM … Here are the differences in averages of the 7mm Rem Mag vs .300 Win Mag; 300yds (.34”), 400yds (1.32”), 500yds (2.62”), 600yds (3.08”), and 700yds (6.96”). Both of these rounds produce enough KE to create a lot of damage on the largest North American game at all ranges most hunting shots are taken. If we look at the averages of the two cartridges at the muzzle and 500 yards, we can see how much this gap closes. That introduction was, I’m guessing, retaliation against Remington’s 1962 release of its equally famous 7mm Remington Magnum. The 175 grain bullet worked well on Elk and caribou for me. 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. The physics and math behind the ballistic coefficient and its implications, while interesting, is not something we are going to attempt to convey in this article, but we do urge you to check it out. More Guns. Handgun Back. There are several factors that influence the amount of penetration that is going to occur, other than the type of animal. Mag. Both cartridges have their rounds with heavier bullets and subsequent higher SDs. If you want a flat shooting round for short hunting situations, both the 7mm RM and the .300 WM are going to get the job done. We put 3 popular cartridges to a head-to-head-to-head test. 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. Both cartridges also have heavy enough bullets and the terminal ballistics to be used for larger game such as elk, moose, and more exotic game and still have a wide effective range. It does give you a better idea of which cartridge has more options for higher performance numbers for each specific category. We also do not see any overlap between rounds of different cartridges until the 500 yard mark, and even then, it is only the highest performing 7mm RM round that matches the lowest performing .300 WM round. The .300 Win Mag is not only a hunting caliber but is also favored by long range competitive shooters. The .300 Win Mag rounds show a slightly higher sectional density than the 7mm Rem Mag rounds. 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. That’s the year Winchester brought to market its now famous 300 Winchester Magnum. From this graph, it is easy to see that these two cartridges show very similar trajectories out to 500 yards. Both cartridges maintain supersonic speeds over a 500-yard range and will maintain that rating over several hundred more yards. We don’t think there is any difference in availability between the two, though there is less compared to other popular hunting rounds. The heavier, larger caliber bullet delivers more energy at all ranges despite starting with a slower MV. And like we have mentioned before, using a proper bullet and putting it in the right spot can make up for lack of energy. Size matters, so let’s stick to the two older magnums. Of course, it might also tell us that both are more than capable of doing the same thing efficiently and effectively. 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. And if you need some extra power at short range the differences are nowhere enough to make you decide against the .300 Win Mag. This is an extremely popular caliber for long-range shooters including those chasing big game. The case is based off a .300 WSM with a narrowed neck to fit .284 inch bullets on a .321 inch neck and the parent case is the .404 Jeffery. Discussion Starter • #1 • Mar 20, 2009. Because of this, it will be interesting to see how these two cartridges stack up in various performance categories. When the powder in the casing is ignited, and the bullet is forced down the barrel and down range, that energy created from the burning powder is carried by the bullet. While we will not be graphing all of these rounds (that would be a nightmare for your eyes) we have calculated averages for both and will present those at the end of each section. Meaning, how well can the object, a bullet in this case, overcome resistance and keep moving forward. Below, you will find the numbers for the larger data set. Even with today’s rifle optics, you can ask anyone whether adjusting for a 45″ drop or a 65″ drop is easier and 45″ will be the answer every time. (Or read this article for another take on magnums.). The 300 WSM will have more recoil than you presently have, but put on a Vais muzzle brake and recoil will … Let’s take a look at the averages of the full data sets. When comparing to other popular hunting rounds, including other 30-cal bullets the .300 Win Mag is a newcomer. 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. Those are always the deciding factors: right bullet, right place. Let’s run a quick ballistic comparison and see the tale of the tape. And though it is fine for looking at now, when making your final decision on a specific round, it is important that you take into account all of the factors. You will find these tables at the end of each section throughout the article. As the species increase in size so does the amount of energy. Bullet: 7.2mm 4.
