I have a 308 win match rifle and am wanting to shoot the Berger 185 Match, 168 Hybrids, and the Hornady 178 BTHP bullets.

Anyone have any info on the freebore spec I need for the reamer design so that the shank of bullet is above the neck/shoulder point to avoid the donut from forming and to allow more powder in the load with the listed bullets?

Thanks for any help
