If you’re recoil sensitive…. That changes the ballistics significantly in favor of the 7mm and might alter your plans. 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. That changes the ballistics significantly in favor of the 7mm and might alter your plans. With the larger sample size, we see the same trend that we saw above. Given that, I would happily and eagerly hunt anything with either cartridge — even charging brown bears. 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. Quite a few factors can influence the recoil such as bullet weight, the amount of powder, as well as the firearm weight. Receive our newsletter with the best articles covering guides, guns & gear. We also hope that you have come to the same conclusion as we have after researching these two cartridges. Of course, it might also tell us that both are more than capable of doing the same thing efficiently and effectively. 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. 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. Both the 7mm Rem Mag and the .300 Win Mag can be used for medium sized game such as deer, hogs, antelope, and sheep at just about any realistic hunting range. We think that most of you here reading this article would easily adjust to the increased recoil of the .300 Win Mag, but there might be some who could easily be thrown off by the kick. Though, for hunting purposes, just about all of the rounds for these two cartridges are going to be designed to hold together well and over controlled expansion. 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. We don’t think there is any difference in availability between the two, though there is less compared to other popular hunting rounds. The 7mm is a belted cartridge and the 300wsm is a rimmed cartridge. 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. Either will neatly terminate deer, sheep, elk and larger game so long at the shooter delivers the right bullet to the right spot. The 7mm Rem Mag has become over recent years, one of the most popular magnum rounds on the market for hunting purposes. Higher BC rounds tend to have flatter trajectories. We've got you covered. From the muzzle out to 300 yards, all of the .300 Win Mag rounds show higher bullet energy than the 7mm Rem Mag rounds. A rule of thumb that a lot of shooters go by is that 20ft.lb of recoil energy can influence the shot and even be uncomfortable for some shooters. Let’s take a look at the larger sample set and see how the two compare. A mature bull moose is going to require more penetration than a whitetail deer. While the .300 Win Mag overall has higher bullet energy, the differences are not too extreme. 7mm Remington Magnum (7.2x64mm) 1. 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. The belted cartridge is not going to be quite as accurate as a rimmed cartridge by design.

Because of this, we can easily compare two cartridges rather than having to look at the individual bullet types used. In the larger data set, the .300 Win Mag had a .006 advantage over the 7mm RM rounds. of this 210-grain .308 bullet helps it resist air drag, enabling it to retain more of the energy it started out with. 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. 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. This transfer is also affected by how the bullet reacts on impact, such as how the bullet expands. The difference between the highest .300 Win Mag and the lowest 7mm Rem Mag round is even more drastic with a difference of 615ft.lb of force. As the species increase in size so does the amount of energy. Trying to determine which cartridge is more accurate is always a task that makes us feel a little dirty. And you can’t discount the role recoil can play in accuracy. 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. The higher the sectional density, the less resistance the bullet encounters because of the smaller area that is interacting with the target. It is important to remember when looking at these averages, that they are just averages and you’re not shooting averages out the barrel. We put 3 popular cartridges to a head-to-head-to-head test. We kept both of these cartridges with being fired with a 9lb firearm, and the powder loads were selected from load data. It might be a bit of overkill for medium sized game and you might get a bit more damaged meat, but there is little doubt that it will put them down. Base: 13.0 mm .30-06 Springfield (7.62×63mm) 1.

We have to cut it off somewhere. The ballistic coefficient is derived from an equation that includes input variables from specific cartridge specifications including bullet dimensions and velocity. Mag. Each cartridge has cheaper boxes of ammunition and each has more expensive boxes. Not only are you taking into account elevation but wind as well. Compare all .300 ammunition manufacturers on one easy to read chart. 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.

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. 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. We first notice that the caliber of bullets that the casings will accept are different. Both cartridges have their rounds with heavier bullets and subsequent higher SDs. 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. 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. 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. Most brands offer 170 to 175-grain options in 7mm RM. None of this matters to the elk. For penetration, we will actually look at two different metrics, the sectional density and the bullet momentum. Both are excellent cartridges. 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. In the table below I used the term "mid-range trajectory," abbreviated "MRT." Discussion Starter • #1 • Mar 20, 2009. It’s all nitpicking to us. We did feel the need to mention it, but both the 7mm Rem Mag and the .300 Win Mag cartridges can drive nails with some practice on your end, and they can do it from a distance.
