dryfiring

Concerned about flatting a firing pin, is it bad to dryfire a rimfire?

I’ve always heard it is hard on the receiver since there is no rim to cushion the impact. You can always load empties and dry fire on them.

I've always don't do it on rimfires.

Not an expert, but based on my limited knowledge and experience, I think the concern would be more likely to score/scratch the empty chamber from the firing pin, rather than flatten it.
I've seen a few DA rimfire revolvers with pecker marks on the rear of the cylinder, too. Being a little out of time doesn't help that either.
Of course this could also lead to damaged firing pins.

Well it all depends (typical in life)… individual circumstances determine the situation. Some .22s are ok to dryfire (Glock 44 for example) but I’d say the majority of .22lr guns should NOT be dry fired. Especially when you can use spent casings or drywall anchors as almost free snap caps. No need to risk it

Absolutely. And it's the damage to the rim of the chamber that is the real issue.

The occasional occurance is usually fine. But doing it repeatedly usually causes damage.
