[QUOTE="pineywoods, post: 1219813, member: 48843"] I need to get a chronograph & check velocities...period. I'm still a bit confused about the freebore thing though. The distance a bullet is from the lands is a given- regardless of freebore. With the exception of Barnes & Berger bullets, Most folks are seating .010 to .015 off the lands or touching. Are you saying overbore calibers benefit from more bullet jump with a longer throat? It would seem next to impossible to get a bullet touching the lands in a rifle with more freebore. This almost seems like an advantage in my rifle, particularly with 85 to 100 gr bullets. Isn't pressure correlated to bullet distance from lands ? How does freebore play into ?I'm probably confused.... Basically, if I keep the rifle as is, the worst thing that can happen is a slight loss of velocity. I really hate to mess with a gun that shoots so well. I'll assume reaming the throat out for more freebore could cause an accuracy issue if not done absolutely correct. [/QUOTE]
