I'd probably just go to Lowe's and get a 3/16" hardwood dowel, stick it down the barrel and pound the bullet out. The wood dowel won't harm your barrel no matter how hard you beat on it, and the bullet won't either. Just be careful of the crown of the muzzle. The wood shouldn't harm it either, but one can never be too careful. If possible, go at it from the chamber end, with a bore guide if you have one. But if the bullet is stuck in the first few inches of barrel, you might be better off going form the muzzle. A little penetrating oil might make it a little easier too, just make sure you clean the bore well before you shoot it again.

Goldensaber beat me to the draw! What he said!
