Handgun ammunition has 50 rounds to a box unless it is a security load, then it will usually be 20 rounds.  Security loads usually have a HP hollow point.Some jhp come 50 to a box, but not usually.  Some boxes are value packed for a 100 or 200.   FMJ full metal jacket is your ball ammo for practice.    If you need something special, I can try and order.  Special order ammo tends to be more than regular calibers when I get it.  Call or come in and check it out.
