I’ve got two AR’s in 7.62x39 and I’ve shot a bunch of steel case through them with zero problems. Also have a bunch of Fiocchi brass case I bought mainly for the brass. Wolf 125 grain soft point steel case is extremely accurate in both and 200 FPS faster than the Fiocchi. The Wolf is a great deer round, and very inexpensive, so I don’t see much need to reload. It’s there if I need it though, and in the present climate it may get some use.
