Looking for thoughts and input on a semi auto rifle that fires the 7.62 x 39 mm round. Would like it to cycle steel-cased ammo (Tula, Red Ops, Wolf, etc.). I kind of prefer the AR platform (PSA makes a nice one), but can't seem to locate one. The Ruger Mini 30 is intriguing (pricey too.), but many complain that it will not cycle steel-cased ammo. I know very little about the SKS and AK-47. Appreciate any input you may have. Intended uses - target plinking, varmints, hogs.
