[QUOTE="kiwi3006, post: 321542, member: 8927"] I was speaking to a guy once who shortened a barrel so he could fit a suppressor on it. Once it had been shortened the accuracy decreased. He put it down to the projectile doing less than one and a half revolutions while in the barrel. ie a 1 in 12 twist needs to be 18 inches long to get 1.5 revolutions in the barrel. Anyone else heard of this? Or was it more likely a poor crowning job when the barrel was shortened? Stu. [/QUOTE]
