.312 for 300 BLK?
 

Ok so I have about (75) .312 147gr I pulled from some 7.62X54R that the primers were corroded. They were berdan primed so the brass went to the scrap and the powder went to the un-known powder jug. I don't reload 7.62x54R or 7mm Jap. so I have these projectiles and need a home for them. I know .38 Special ranges from .355-358. I reload Blackout and those are .308, so would .312 work? Hmmm

No, Nyet, Nein!

Pressures would run way too high. Would likely blow up the gun.
