[QUOTE="LB, post: 36493, member: 2721"] Yes, but maybe the only thing you will have proved is that you moved your max load upward, due to the increased volume, or expansion room. I'm sure that you understand that a constant charge weight produces different velocities, in different barrels. A max load of eightly grains producing 3200 fps in one barrel; may require 80.5 grains, in another barrel, to reach the same maximum pressure and the same velocity. Ten barrels, velocities recorded, and then rechambered with a larger reamer might give you some indications, if every one showed the same improvement. Simple things always get complicated. [/QUOTE]
