Re: Bullets and Barrel Twist? Help
I have a 240 Gibbs, Shilen 30" 8 twist, it loves 115 gr Berger's, pushing them out at about 3,230 fps.
It takes a certain RPM to stabilize any given bullet and most of the "Twist Rates" given by the manufacturers are for nominal velocities, so when you are pushing them faster you can get away with a little less twist.
Be warned that the "standard" Bergers don't like anything much above 3,300 fps, and when the throat starts to get a little rough even at 3,200 they some times blow up.
