Hmm... you got me there. I don't buy any domestically produced commercial ammo... all the junk I buy is old milsurp stuff (8mm Mauser, 6.5 Carcano, 7.62x54R, etc) or foriegn commercial stuff (S&B 7.62x54R, 7.62x39mm)

The best I can say is buy as many boxes of different brands as you can get and try them yourself. Try to stick to softpoints for self defense until you can figure out if the gun will digest hollowpoints and the like with 100% reliability.
