+1, there are only a handfull that you can, and I believe most are semis. The 10/22 is one of the few.The 10/22 is designed to be dry fired, most other rimfires are not.
I don't think I would do it, because I am pretty sure it will peen and chip (over time) if you do.What do you guys think?
Fine to fire on brass, and the 870 will be fine because it is centerfire. I am not aware of any centerfire that can be damaged by dry firing.If I dry-fire on used brass it's okay thought right? I dry fire my Rem 870 all the time, is that going to hurt it as well?
I haven't heard of any centerfire guns that are harmed by dry-firing, but I am not a smith and am not certain. IIRC you should not dry-fire OU/side-by-side shotguns, but I am not certain as to why. I wouldn't (and try to avoid it myself) dry fire any of them because it is not necessarily good for any of them, but neither is leaving the firing pin cocked. Snap caps are a good investment IMO.I always understood that pump shotguns shouldn't be dry fired.
