Problem with these clips is availability of originals. They were around, and no one cared. Now they're wanted and most are reproductions. I've had problems with the bolt action not co-operating and one firer took the very tip off his thumb loading...that hurt. The TT rifle wasn't so bad. Shot nicer too...it's a matter of getting some that work and treating them like gold I think. If one can get older Russian clips it might be worth it.
