[QUOTE="budlight, post: 1815649, member: 2939"] I have 1:9 and a 29 inch barrel. I was looking at a 27 Nosler last month and it was something like 8.5 twist. I was able to shoot up to 175 or 169.5 which i have the most pills of. The 190's were no go! I wish that i had the formula to post. twist is preferable over trying to attempt additional FPS in getting a bullet to stabilize. cold weather will screw a bullet with marginal RPM [/QUOTE]
