I stopped shooting my grandad’s single shot .22 rifle (from the 1920’s) because the shells would stick after just a few rounds. About 45 min later the shell would come out easily.
Then I had the same problem with a Ruger single action .22 revolver my dad bought in the late 1950’s.
I took my grandad’s single shot .22 rifle to a gunsmith and he found nothing wrong. He said I needed low power shells for vintage guns. Modern ammo stresses them too much.
This was a couple decades ago and I never did track down any low power ammo. Do they still make it for a vintage .22?
