using 308 for 7.62x39

level10 · May 15, 2012, 09:15 PM

I am not sure if this is correct but i heard you could use 308 projectiles 130 gr or less for 7.62 x39 that usually uses a 311 bullets . Has anyone here actually done this and does it perform well? thanks for any replies

You can do it but it does not work well, at least that was my experience with a Mini-30.

More specifically, I never shot them across the chronograph but the rounds seemed full power and cycled fine but the accuracy was much worse than the .311 bullets that I use.

Both my SKS rifle have .312 groove bores,I tired a few different .308 dia. bullet in both rifle and accuracy wasn't as good as steel case Russian ammo. I get the best results with .310 dia. bullets followed by the .311's in jacketed bullets and .314 dia. with cast lead.

They will work and work safely as long as you follow safe loading procedures, but accuracy may suffer. Some have had acceptable to good accuracy, most have not.
