300 short mag ballistics

The 270 WSM is by no means rare though and most sporting goods stores carry ammunition for both cartridges. The differences in external dimensions between the .270 Winchester and 270 WSM obvious in the photo below. 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. And by lighter, it’s usually around half a pound to a pound difference in weight. 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. [12] It is particularly useful when hunting the members of the ungulate family such as elk and moose and is a popular cartridge among hunters for these class 3 game species. This is very important for long-range shots, which these cartridges are often used for. Looking at the recoil of the .300 Win Mag vs .300 WSM is important for understanding certain situations that you might favor one over the other. Compared with the 30-06 Springfield the .300 Winchester Magnum provides a roughly 400 ft/s (120 m/s) increase in velocity. The first three cartridges were all designed and marketed specifically as short action alternatives to extremely popular and effective standard length cartridges: the .270 Winchester for the .270 Winchester Short Magnum, the 7mm Remington Magnum for the 7mm Winchester Short Magnum, and the .300 Winchester Magnum for the 300 Winchester Short Magnum. The difference between the two averages remains just about constant as the rounds move downrange to the 500-yard mark where the averages for the WM and WSM are 58.2lb/f.s and 22.3lb/f.s respectively. Still less than two inches. At the same time, the 300 WSM is the most popular Winchester Short Magnum cartridge and is also extremely commonly used as well. Don’t confuse that with the “kick” that you feel when shooting. slugs. Are you just itching to take a rifle chambered in one of these cartridges on a hunt? The cartridge is also able to be to take a variety of bullet weights. Both cartridges normally use bullets in 150-230 grain range. Most hunters/marksmen want a flat shooting round. Velocity, when paired with the correct barrel twist can make the bullet more stable. SAAMI recommends a bore diameter of 7.6 millimetres (0.300 in) and a groove diameter of 7.8 millimetres (0.308 in). This results in a little bit less recoil. We have calculated the bullet momentum by using the bullet’s mass and velocity for each round and graphed them below (Graph 9). Almost no divergence between C.I.P. These bullets need a proper amount of speed to get the correct terminal ballistics. The introduction of the .300 Winchester Magnum was not unforeseen; rather, its introduction was anticlimactic. Unfortunately, the future isn’t looking very bright for that cartridge right now. Those heavy rounds at 1,000+ yards appear to bring the average down a good bit at this range. 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”. Although the .300 H&H Magnum, .30-338 Winchester Magnum and the .308 Norma Magnum had a head start on the .300 Winchester Magnum these cartridges soon faded into obsolescence. [3], The .300 Winchester is extremely versatile and has been adopted by a wide range of users including hunters, target shooters, military units, and law enforcement departments.
