i had that happen with my sig 220 had a reload sans powder. the primer shoved it just far enough to fully lodge in the rifling. i took a punch held the punch and barrel in one hand and smacked witha hammer with the other. took me an hour to get the bullet out one smack reset recenter the punch another smack.
Wooden dowel and a small hammer. Insert the wooden<WOODEN dowel in the barrel from the back side where the bullet enters(breech) until it rests on the bullet. Then, using a small hammer, tap the dowel until the bullet falls through. Dont send it back down the barrel.
I want to be a ball turret gunner.
