What some people like to insist upon in the. The genesis of those claims was an army test conducted in the s. The military pitted two match rifles in those chamberings against each other, using match ammunition, and the. People have been quoting or pointing to these tests as proof of. Back when people used typewriters, that was something. The gap has narrowed to nil. A quality rifle in. Both are excellent target rounds, and - with quality ammunition - can reach out and touch something out to 1, yards.
Both are excellent hunting rounds, and have been used to put almost every land-based game animal in the freezer at one point or another. Both are still among the most popular North American game cartridges in production, and for good reason.
Either will harvest everything from hogs to deer, all the way up to moose and black bear; if you wanted to be a one-gun hunter,. So, if there's only slight differences between the two cartridges, is there any reason to pick one over the other?
Here's where. There are far more compact bolt-action rifles offered in. Standard bolt-action rifles, with a inch or inch barrel, are only 0. Because of the length of the cartridge,. There are some, to be sure, but they aren't common and aren't cheap. On the other hand, you can find ARs and other modern sporting rifles in. Since the modern shooter is obsessed with everything tactical, that's likely a bit of a deal-breaker.
You could get yourself an M1 Garand, but it's not an AR and AR-platform rifles are what people tend to like these days. And what does. The Military first adopted it in Before designing the. This new design could achieve a fps muzzle velocity. However, at that time, most Militaries across Europe were adopting lighter and higher velocity rounds.
The cartridge was becoming obsolete, and the US military had to act fast. The case was modified to fire a gr bullet.
The resulting. The lighter round without losing velocity was ideal for the military. A soldier could carry more ammunition and rifles could be made lighter. They also used less material in their production. It was later replaced by the 7. The lever-action M Winchester was the first commercial rifle ever chambered for. The original Springfield military rifle in.
Recoil energy of Modern rifles in. Recoil of a grain bullet from a 7-pound. With its original grain spire point bullet at 2, fps, the Springfield. A flip up rear leaf sight was graduated for ranges out to 2, yards. Point-blank range for a standing, man-sized target was yards. Whether the military rifles were accurate enough to take advantage of this is moot. Im sure a few were, most were not. The flight of the bullet is the whole reason for the rifle, scope, primer, brass, and powder.
The faster a bullet leaves the muzzle and the higher its Ballistic Coefficient, the flatter it shoots, the less it deflects in the wind, and the more energy it retains at all ranges. Given the same MV and B. Putting that bullet in the correct place is the final piece of the puzzle see Accuracy above. Think about all this for a minute.
Muzzle velocity, B. Shorten one and you shorten performance. Lengthen one, and you increase performance. This is how some seemingly smaller calibers and lighter bullets can outperform large, heavier ones. Increased velocity and mass increase powder consumption, recoil, and expense. In any given caliber, increased velocity decreases barrel life. That means we zero bullet impact as high as needed usually about 3 inches at yards to ensure bullets strike no higher than 4 inches above the aiming point at peak trajectory usually around yards.
In addition, we will select appropriate bullet weights for deer hunting and attempt to keep bullet B. Be aware that lighter, heavier, or better B. Increasing bullet weight to increase kinetic energy downrange punch always requires a sacrifice of MV. With a consistent form factor boat tail spire point, for instance additional weight reduces muzzle velocity, increases B. Here are the trajectories and downrange energies for some of the above bullets.
Not every rifle will hit these exact MVs, and changing to higher B. Notice how higher B. The most revealing takeaway from these numbers is how similar all cartridges perform at yards. Energy levels are more than adequate even for addressing big bull elk. This civilian version of the military cartridge 7. That means the rifle can be a half-inch shorter, maybe 4 ounces lighter, and 0.
