Glasers are a light bullet, high velocity, instant stop(?) load, and kind of pricey,but worth the money, if it gets deep.
Any decent gunshop will fix you up.
AGAIN- CHECK THE FEEDING. The best empty gun around is only a blunt weapon.
P.S. the bullet is a load of #12 shot, in suspension, eliminating ricochet, and overpenetration, entirely. Really good stuff!
