After all, the .300 Win Mag is a rifle that has become known for its versatility and precision; hard hitting power and its accuracy. The physics just doesn’t allow them to stay as flat while still being manageable in other categories. For hunting large game, you would want more momentum to be able to push through thicker hide and bones which are denser and provide more resistance. If we look at the averages, the .300 Win Mag rounds have a slightly higher BC at .553 while the .300 WSM has an average of .520. And by flat we mean there is a less pronounced drop in elevation over time. There is a definite difference between the .300 Win Mag and .300 WSM with all of the .300 Win Mag rounds generating over 26ft.lbs of energy with several in the 29-32ft.lb range. If you look individually, there are better performing rounds for both cartridges. And that change in the difference is mostly due to the.300 WM Trophy bonded ammo from Federal which only has a bullet drop of 6.6”. Mag. Again, even with more cartridges in play, we see the same trend pop up between these two cartridges. Don’t confuse that with the “kick” that you feel when shooting. Momentum simply describes the ability of an object in motion to stay in motion. Both also have round options with very high ballistic coefficients which is always beneficial when you start dealing with higher wind speeds and 500+ yard shots. Like everything we have covered, it all depends on what you’re shooting at, and we will discuss this more when we get to the applications of these cartridges. These high-velocity rounds also means a little extra kick. That performance can give us some indication of how difficult it might be to place the bullet in the vitals or the bullseye. Not just .300 WM to .300 WSM round, but between rounds of the same cartridge type. Get our PDF with 13 pistol & rifle targets (worth $48) including expert instructions for FREE! Some of this reduced weight often comes from using a shorter barrel, and there are a lot of arguments out there for longer barrels increasing the accuracy of the round. 300 PRC vs 300 WIN MAG!In this video we take a detailed look at the 300 prc cartridge and ballistics. What it all comes down to between these cartridges from a ballistic/performance standpoint is personal preference, in our opinion. If we take a look (Graph 4) it’s difficult to tell if there are even two separate lines. This round is also top of the list when it comes to muzzle velocity. The 2001 release of the .300 Winchester Short Magnum (WSM) saw the first serious threat to the hallowed .300 Winchester Magnum since its release in 1963. There can be no doubt that both are outstanding rifle cartridges. From the muzzle out to 200 yards, all of the rounds group pretty tightly together but we do see the two .300 Win Mag rounds show slightly higher energy than the other eight rounds. There are obviously more options out there but ten felt like a nice round number that wouldn’t make things to cluttered. While the .300 WSM has a slightly longer supersonic flight than the .300 WM, on average, it is only by thirty yards. We do have to remember that there are some pretty distinct differences between the two cartridges so it is important to take a close look at as many ballistic categories as we can. in the 1940s, and in 1963 Winchester introduced the.300 Win. This specific cartridge came into production by Winchester in 1963, so this, when compared to other popular hunting cartridges, is fairly new though quite a bit older than the other cartridge we are looking at in this article. Like any hunting cartridge, it’s all about matching the style of ammo with the hunting situation when thinking about its effectiveness. Based (loosely) on the .404 Jeffery case, and shortened to 2.100 inches, the beltless .300 WSM gave velocities nearly on par with its older brother in a shorter, lighter and more rigid rifle. On top of that, this round has an incredibly flat trajectory at 300 and even 500 yards and a BC of .597 which will make things a bit easier when dealing with less than ideal wind conditions in the field. Compare 300 magnum ammo from the top online retailers to find the lowest price. These bullets need a proper amount of speed to get the correct terminal ballistics. Mag.’s 25-degree shoulder. When we look at the full data set, we see that the .300 Win Mag rounds still have a slight advantage over the .300 WSM, though the difference between the averages has tightened. This is very important for long-range shots, which these cartridges are often used for. We have compiled each of the ten round’s BC and graphed them here (Graph 3). For long range shooting or chasing a bull moose, both of these cartridges, when shot with confidence and skill, are going to put meat in the freezer. From these numbers, we don’t see huge differences between the two cartridge types. Most bullets designed for hunting expand on impact to create a more damaging wound and give optimal transfer of force to the surrounding tissue. The .300 Win Mag burns 20% to 25% more powder than the .30-06 Springfield, which gives it a 10% increase in velocity, as long as it is firing bullets of the same weight. Before getting into the specifics, if we just look at the graph, several points of discussion come up.

Just by looking at the bullet and casing specs of these two cartridges we can begin drawing some inferences about how these two cartridges will perform. .300 Win Mag rounds are often a bit heavier than the more popular .300 WSM rounds. When getting into trajectory with ten different rounds, all with different powder charges and bullet weights it can get pretty cluttered in the discussion. Below we have listed the average recoil energy from all forty rounds we have compiled. The .300 WSM rounds are not too far off staying in the range of 24 to 26ft.lb range. Even at 500 yards this round still carries 2,016ft.lbs of energy, so range and stopping power is not an issue even for larger game. Now i know with the right bullet the 7mm will do everything i need and at good ranges too. From this standpoint of just looking at computer generated data, there is nothing really to discuss between these two cartridges are short range when looking at trajectory. For factory loads, both of these cartridges bring pretty impressive trajectories. How this translates to bullets and stopping power is the more momentum a bullet has, the more it is going to take to stop the bullet. I currently have both a 700 Remington and a M77 Ruger type rifles. These heavier bullets provide more penetration and stopping power that is always appreciated when taking down large game. And this is one of the reasons why we wanted to include the numbers for a larger data set in the event that something like this would happen. Both of these cartridges remain in supersonic flight out past the 1200 yard mark. The .300 WSM is one of the more popular short magnum cartridges that have come out in the last two decades. We mentioned that the .300 WSM is often used in shorter, lighter rifles. 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. In reality, most rifles chambered for the .300 WSM are often a little lighter with them having a short action. Lighter rifles often mean a little extra recoil energy that is generated so the numbers might be a little higher for the .300 WSM rounds. 7mm Rem Mag vs 300 Win Mag Conclusion. We calculated the sectional density numbers for the ten rounds and listed them in graph form below (Graph 8). Again, like most of the other categories, there is a lot of overlap between the two cartridge types, at least with the rounds we have selected. Factory loads tend to err on the side of caution when it comes to loading the casings with powder. It bettered the velocity of the benchmark .30-06 Springfield by over 200 fps, yet could fit in a standard long action. If we take it out to the 400-yard mark, we are still talking about an average right at the 2,000ft.lb mark which exceeds the general limit you need for big North American game. It’s always good to look into the similarities and differences of two cartridges, but at times, your decision really should be made based on other factors. It also gives us something to look back on when we see the numbers and help us make more sense of them. Which is several inches better than any of the other Win Mag and WSM rounds. In fact, when we look at the averages of these rounds we see that there was less was never more than an inch difference in bullet drop in the short or long range trajectory data. Just looking at the muzzle velocities, we see three rounds that outperform the others with two of them being .300 WSM rounds and one .300 Win Mag round. At the 600 and 700 yards, we start to see gaps form between the two rounds, but like the short range trajectory data, there doesn’t seem to be any pattern in how the rounds from each cartridge group together. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bullet weight, or jacketing type. Receive our newsletter with the best articles covering guides, guns & gear. It influences just about every performance spec that is often discussed when looking at different cartridges. Deeper penetration is not always an indicator of a better cartridge. As illustrated in the chart, .300 Weatherby Magnum rounds - on average - achieve a velocity of about 3230 feet per second (fps) while .300 WSM Winchester Short Magnum rounds travel at a velocity of 3080 fps. It’s still something to think about even if you do have a lot of experience. Velocity. The most notable difference between the two rounds, however, is the weight and size of the bullets they fire. Mag. The SD is derived from a calculation using the bullet’s diameter and weight. Both of these cartridges showed pretty impressive trajectories for factory loads with an average of 6.64″, 19.2″, and 100.9″ at the 300, 400, and 700-yard mark. We are not under the impression, nor do we want to make the impression, that all rounds available are going to fall within this range. From the muzzle out to 200 yards, the .300 WMS has a slight advantage when looking at the averages though the difference is less than 100fps. Please click the above links to take a look at all of the .300 Weatherby Magnum and .300 WSM Winchester Short Magnum ammo we have in stock and ready to ship, and let us know any parting thoughts in the comment section below. Both the .300 Win. And one final issue that we want to bring up is the barrel length. And that is usually a tradeoff you get with heavier rounds. If you are on the range, we like the .300 WSM Barnes VOR-TX TTSX 165gr round. Likewise the standard length .308 Norma magnum. The .300 Win Mag takes a 30-cal bullet as does the .300 WSM. Which is most definitely the case when looking at the .300 WM and .300 WSM cartridges. Interestingly, we do see a little more separation between these two cartridges at the 1,000 yard range. If we look at individual rounds, the .300 WSM has two round at .45 and below while the .300 Win Mag only has one that falls below .5. Knowing how the round performs let’s you understand if it will fit the hunting or shooting situation at hand. For hunting purposes, which both of these cartridges are used for, all the ballistic data is important, but if they can’t bring down big and thick hided game, it isn’t going to matter if the bullet gets there. For large and even dangerous game this is an excellent round. It’s not that you can’t get what you want of the .300 WSM, but you might have to shop around more for it. It has an incredibly flat trajectory out to 300 yards and is even manageable at the 400-yard range when the adrenaline is pumping with a ballistic coefficient of 0.64. The .300 BLK is suitable for hunting deer, but for larger game like bear or elk you’ll want the extra power of the .300 Win Mag. And this is only five rounds for each cartridge. Both cartridges have several rounds in the .25 to .3 range though the .300 Win Mag on average has a slightly higher sectional density. We also do not see the rounds for each cartridge grouping together. We used a ballistic calculator to generate the recoil energy generated from firing these ten rounds (Graph 1). Outside of the bullet design, which is going to provide controlled expansion to deliver penetration as well as deliver the huge amount of kinetic energy this bullet carries, it also carries a ton of momentum. With these two cartridges, we are more interested in the energy once we get out to the 100-300 yard range and beyond. The .300 WSM offered shooters, and still does, the power of the popular .300 WM while allowing the user to use a short action rifle that is a little lighter. Of course, bullet design (including sectional density) and expansion also influence a rounds ability to penetrate. As you can see, 6.5 Creedmoor is generally much cheaper than.300 Win Mag. We will also compile this data in the applications section. The velocity as well as the design of the bullet factor in as well. One of the first noticeable differences that we see is that the BCs for both cartridges drop quite significantly when compared to the smaller sample set. We have also added in a 400 yard marker for further comparison. Trajectory In the simplest of terms, the ballistic coefficient is a number that is derived from an equation taking into account a variety of bullet flight specs. This round is popular for long-range shooters including big game hunters and competitive shooters. Both of these cartridges are a bit more expensive than other centerfire cartridges, but they also bring a lot more to the table regarding stopping power and ballistics. So, the .300 Win Mag is slightly more powerful, has a slightly flatter trajectory, and has somewhat more recoil than the .30-06. We do think that the amount of energy a bullet is carrying is important to know and understand when using these rounds for hunting purposes, but we also know that those guidelines are arbitrary. We have a variety of deals on Rifle Ammo, Handgun Ammo, Shotgun Ammo & Rimfire Ammo, as well as ammo for target practice, plinking, hunting, or shooting competitions. The .300 Winchester Magnum—that belted affair based on a shortened Holland and Holland case—was released in 1963 as the last in a quartet of cartridges that redefined magnum performance to the masses. Our website lists special deals on 9mm Ammo, 10mm Ammo, 45-70 Ammo, 6.5 Creedmoor ammo, 300 Blackout Ammo, 10mm Ammo, 5.56 Ammo, Underwood Ammo, Buffalo Bore Ammo and more special deals on bulk ammo. The first rifle on our list of best .300 Win Mag rifles is the Model … The velocity and BC both affect the trajectory of the bullet as does gravity and wind resistance. Unlike my 308 vs 30-06 article, this one is NOT splitting hairs. In general, anything over 20ft.lb of recoil is enough to impact shot placement, though that is pretty relative to who is handling the rifle. Keep this information in mind as we start to look at the actual data comparing these two rounds. Mag., it … The .300 WSM achieves what its designers intended, duplicating the velocities of the .300 Win Mag from a short, lightweight rifle platform. Most weights are within the 150-200 grain range, but there are several lighter and heavier rounds available. This is mainly due to feeding issues with the shorter actions of .300 WSM chambered rifles. and the .308 Win. Because of that, we will strictly focus on energy that the bullet carries and will be transferred to the target and the potential amount of penetration you will get on the target. If you go out to the 400 yard mark, the .300 WSM rounds have an average of 0.7 inches of bullet loss. The majority of the data is available from the manufacturer, and where that was not available, we relied on ballistic calculators from trusted sources. When it comes to this type of data, there is no concern with comparing cartridges, but you should be aware that these numbers can change when being fired from your rifle. Sniper Country is reader-supported. In the Federal Vital-Shok, 6.5 Creedmor works out to $1.72/round, while.300 Win Mag comes out to $2.40/round. A lot of people who have narrowed down their selection to these two cartridges are probably more interested in how these two compare at longer ranges. Velocity is also important when it comes to stopping power. Sectional density plays a role in momentum as more momentum is conserved when the projectile, a bullet in our case, is striking a smaller area. It’s no sleight, and we have not made the statement that these are the best available rounds available. The advantage to this round is the ballistics are nearly identical to the .300 Winchester Magnum ,  but in a lighter rifle with a shorter action burning 8 - 10% less gun powder. To get a little better idea of how the two compare, let’s look at the averages for our larger sample set. With that, in this set of ten rounds, the flattest round was a .300 Win Mag round, but we also saw a .300 Win Mag round that was the steepest in bullet drop. There are flatter and steeper rounds for each and the steepest is only a little over 12″ at 300 yards, which is more than manageable with today’s rifle optics and a little hard-earned experience. Below, we have listed the average bullet kinetic energy for the 20 rounds of each cartridge that we have compiled. From this data set, the .300 Win Mag still has a slightly higher sectional density than the .300 WSM rounds. The averages show the .300 Win Mag has around half an inch less of altitude loss at the 300 yard mark but when you look at all of the individual rounds, their distribution make all of them seem like the same cartridge type. Those heavy rounds at 1,000+ yards appear to bring the average down a good bit at this range. In choosing between the 300 Ultra Mag vs 300 Win Mag, our choice is the 300 Win Mag because it has less recoil, more affordable, has more factory match loads, and offers more available load data than the 300 Remington Ultra Magnum. That just happens to be the case when looking at the .300 Win Mag vs .300 WSM. Hunting expand on impact to create a more damaging wound and give optimal transfer of force to the range 2,500ft.lb!
