[QUOTE="jrock, post: 1900010, member: 78569"] Long freebore is part of the Weatherby design for speed. It is also part of the 204 Ruger for speed. I have several of them. One 204 is on an AR platform, so I'm restricted on length. The other is in a short action and I seat out to near lands. the second I can add 0.3 grains more powder before hitting pressure and I get about 150 fps more speed. The increase is partly due to 2" longer barrel (~50 fps) and more powder. Beyond that, the internal ballistics are beyond my full understanding. I don't like being restricted by mag lengths. [/QUOTE]
