Current plan is .125 freebore at .0005-.0008 over bullet diameter, then a 1.5 degree throat angle. This basically duplicates the Whelen reamer I came up with. Have shot most of the factory ammo I could get hold of out of that chamber. It's warm, near or at book max, but not over. Various 250gr bullets jam at between 3.34 and 3.35 coal, 225 accubonds jam at 3.45 or so.
On this 9.3 reamer considering adding with .010 more freebore just to make up for the slight increase in case capacity over the Whelen. Thoughts?
