My biggest problem with bump firing anything is that it's the sure fire quickest way to ruin a barrel. Barrel gets hot fast and expands. Gases flow around the bullet in the throat. Throat erosion happens very quickly, and then the gun is good for absolutely nothing but bump firing. Sheesh! When I was into shooting prairie dogs, I would bring 2 varmint rigs, and switch rifles every 20 rounds or so to prevent that. And these were bolt guns!
