YES!! I use 31.5 grains of H335 with a Sierra 150-grain .308" diameter flatbase spitzer in my SKS's and CZ 527 carbine. Plus, it is VERY accurate, even in .311" bores. V = 2300 FPS @ 10' from the muzzle......

Warning!! This load is OVER MAX in several manuals, but has always worked well for me in all the 7.62X39mm rifles I've shot it in, including a Ruger Mini-30! Work up slowly, if you try it.
