Hi guys,
Receintly I started to cast Lyman 311284 boolit for my rifle. I cast pure lead 220 gr. boolit with water quenched base and GC(I haven't got hardness tester). The bore is .311 and has 1/9.45 twist. The cartridge 7.62X39 has COL 2.20. The speed was perfect - 930-950 fps .
I started my shooting session with 10 cartridges. Than came the shock! I coldn't hit the target from 50 yards.The accuracy was terrible. The boolit can't be stabilized.
Were am I wrong? The hardness? The COL or the twist ?
I'd like hear your comments!
