Yeah, especially since a “bullet” is just a lump of inert lead.

Sammi Video on ammo

Written report on ammo no in a chamber
It could happen but the damage from dropping a .22 rifle on you foot may well be more than having a unchambered round go off at you
It’s funny, whenever I cooked off ammo, the bullet tended to remain in place while the casing flew in the other direction. Guess physics has changed since I left Cali.
