Have you guys with these nylons scoped ever try to shoot groups with them?I'd be amazed if you could shoot 1" at 50 yrds. Like I said, mine was all over the place, probably 2 or 3 that would be fairly tight and the next 2 would be all over the paper. If I tried to tighten down the screws on the receiver cover, it would put too much pressure on the receiver and the bolt wouldn't cycle properly. If you don't have this problem then you are lucky. This is a common problem with these, do a search on rimfirecentral.
