Just stay with basic cowboy type loads . Any lead 45lc load under 900 fps will be safe and mild to shot. maybe to far to order but check out georgia arms 45lc loads. there target, cowboy and there larger quanity Canned-heat ammo Some use new starline brass others reloaded. Good ammo over all with prices starting at 25.50 for 50 rounds for new ammo. They sell alot of ammo and avaiblity comes and goes.
