308 ballistics by the inch

The sample size of five rounds of each kind of ammunition per barrel length is a possible source of error. Ballistics by the Inch (often called BBTI) was a project to test the performance characteristics of a variety of common handgun calibers/cartridges. Muzzle: 100 YDS: 200 YDS: Velocity (FPS) 3050: 2691: . This weight is more appropriate for whitetail deer and other small-medium sized game. The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length. Ive been beating on the 510 and 517 for a while. Do you trust the results from the MagnetoSpeed? Is the reverse possible? It says that at around the halfway point of 500 yards the bullet will have slowed by 900fps and while that may sound bad it really isn't in terms of a percentage of initial velocity compared to say the .223 Remington (would be 1481fps from initial 3214fps) or the 7.62x39mm (would be 1066fps from initial 2349fps). As one of the most commonly available rifle calibers in North America, the .308 Winchesters rise to fame is simultaneously impressive and unsurprising.

The barrel was cut off using a cold saw. The cuts were made in one-inch intervals with a rotary saw. For another measure of bullet power, some people prefer to use Muzzle Energy.
