Now semi-automatics would likely get A lot higher, but this was all done for bolt-action rifles and 20 rounds for every minute is a reasonably swift fee of fire.

So when we are able to find to mitigate that variance … at this point, no powder allows you to entirely do away with it. But, it is possible to minimize the result by earning a wise powder choice.
but when you are from that place if gains and looses speed. Testing reveals factors ar enot linear For numerous powders , some have selected temp ranges where practically nothing Significantly transpires after which a steep drop or climb ,you may perhaps avrage that but its not authentic.
You are doing know that any time you alter the temperature on the bullet by that extreme of the mount that the physical measurement in the bullet truly alterations. It’s no wonder the velocities had been different When the diameter from the bullet is .003″ distinct at People two temperatures. To even get fairly correct final results of this concept the actual rifle would have to be heated and cooled concurrently given that the bullets.
