Can a .177 Caliber Pellet Gun shoot a BB without damaging it?

Yes, I had one when I was a kid, it shot both 177 cal pellets and bb's...good shooting to you. just dont go cryin when you muck up your rifle: 7/21/09 The 177 can shoot BB if it is designed to do so. Some models shoot BB and pellets. However if it is not designed to shoot BB's then forcing the gun to do so will damage the rifling in the barrel. BB's are solid and do not deform in the barrel when shot. Pellets flair our when shot through the barrel and the skirt of the pellet uses the rifling to make it spin as it leaves the barrel. BB's wear away this rifling and ruin the accuracy of the rifle. Never shoot BB's in a gun that is not designed for it.
