Thread: Crazy idea #213 :-)

Assuming I can have the 7.62x39 Baikal reamed out to take a 308 case...

I understand that the 7.62x39 bore is .310 or .311, so the chances of .308 projectiles being accurate is not very high.

If I then load 123gr .310 (7.62x39) projectiles or 150gr .311 (303) projectiles, what do I need to do for neck sizing ?

Will a chamfer tool be sufficient to get the 310 or 311 pills started into a case that has been neck sized using 308 dies ?

Or will I need to use a expander die / oversized bushing to flare the case mouth after neck sizing ?

My reloading background is pistol cases, so used to flaring the case mouth and then crimping.

Second question - any comments about using lightish (mid 120 gr) projectiles in 308.
