[QUOTE="jwp475, post: 204547, member: 3776"] I have a friend that works in a Ballistics lab and he ran a test with a 223 Rem with a 7 twist and compaired the pressure and velocity to a 14 twist. After runnig the test he told me that the difference in velocity and pressure between the 7 and 14 twist was insignificant.. Many claim that by running a slow twist that they can increase velocity without increaseing pressure, but judging by this test that is not the case. A fast twist barrel can degrade the jackets and cause problems with some bullet, but not all bullets, such as the Barnes TSX bullets.. [/QUOTE]
