In a 1-30 twist a 200 grain bullet is really pushing the limit. Fortunately 200 grain lead copper bullet is still somewhat short. So it will work very well from the 1-30. When you move to a Barnes or a Bloodline, bullets without lead they get very long very quickly - and in that case the 1-30 can not get them to sabilize without a whole lot of velocity. In a 1-20 stabilize with moderate velocities..
Since the PR's are and all lead bullet - they might be just fine in a 1-30.
Sharpshooter what do the PR's measure in length? Can not imagine that Cecil would build a bullet that would not shoot in most guns on the market.
