Anyone ever patch for 7.62x54R? Any pitfalls in getting a 150-grain, air-cooled COWW projectile up to the standard 2700 to 2800 FPS using, say, IMR 4895?
Planning on sizing to .309, then patching and sizing to .310, .312 or .314, depending on the rifle. Do you think a LLA/JPW mix is going to be OK for the patch lube? What about straight Olive Oil (too thin??)
Thanks!
