I picked up a Mauser HSc imported by Interarms back in the late 60's/early 70's for a few hundred at the Wanenmacher show at the end of last year, I was wondering if anyone else on here owns one? Took it to the range a couple times and I've been having serious feeding issues with it. I've tested it with FMJ including Monarch Brass (PPU) and Speer Lawman, and got the same results. It would chamber the first round, fire, and fail to chamber the next round successfully but allow a trigger pull, imitating a bad primer strike. Ejecting the round and attempting to chamber a new round led to double feeding, etc. It's a mess and I really want to love this gun, it's a beautiful design and the feel is excellent in my hand. Any advice? My biggest suspicion is the magazine, as the feed lips are sharp and may be preventing the next round from being stripped up into the chamber correctly.
