[QUOTE="J E Custom, post: 1686907, member: 2736"] Different bullet designs and makers will take different RPMs and you just have to find the bullet that will handle the velocity/RPM. I have had two rifles that would exceed some bullets ability to stay together. One was a 31" barreled 7 STW that could move a 140 grain bullet beyond 3800 ft/sec velocity. it could push through the 3700 ft/sec barrier but on approach to the 3800 mark the bullets started shedding there jackets as the bullet left the muzzle.I tried other brands of bullets, but they suffered the same problems. I then decided to try mono metal bullets and found the accuracy lacking even though they remained in once piece. The other rifle was/is a 223 WSM in a long barrel that can exceed 4600 ft/sec with the right bullet. all others Give it up around 44 to 4500 ft/sec Twist rates and velocity + bullet construction end up being the deciding factor.
