Thanks all for the good info. I have run fair amount of Ruski steel through 45 ACP, not many apparent problems, but like anything else if its too good to be true (low cost plinking) it probably is. Sure don’t want to turn a fat pistola into a trotline weight.
Thinking about it, I would never buy chinese ammo, why ruski??? Both’s price edge is from dropping quality.
The tradeoffs are that it isn’t as reliable, so you should use it only for practice or plinking. It’s also dirtier, which means more frequent cleaning.
As far as harming your gun...think of all the Makarov and other ComBloc pistols that have run nothing but steel cased 9x18 or 7.62x25 forever. If your .45 is made better than one of those, you’ve got nothing to worry about.
