The blowback design guns,Thompson,MAC 10 & 11,STEN Mark II,MP-40 etc.etc. in 9mm and 45 ACP will work just fine and not give any issues at all as long as you have good bullet to bore fit and use a good lube.
Firearms that use a gas system to cycle the action like the AK,SKS,M1 Garand.AR's and AR10" etc.etc.will function fine in semi-auto mode as long as you don't super heat the bore by firing it in rapid fire succession using cast lead bullets. You can fire hundreds of cast loads in semi-auto rifle without having to clean the gas system but eventually your going to get enough lead.lube and carbon buildup in the gas system to lock it up if you don't clean it,firing cast lead in full auto mode in gas operated weapons just speeds up the process that much faster. Ed Harris once talked about welding the gas system up completely firing cast bullets out of a full auto AK.
I've shot a couple K of 170 gr. gas check lead bullet through my SKS rifles over the years with no issues. There a whole lot cheaper and more acccurate than the Russian ammo.
