I have recently gotten my PTC and have been trying to get to the range at least once a month. I have shot multiple brands names and types of ammo through my pistol (Stoeger Cougar) to see what it would handle. So far it has not had a FTE or FTF. I am wondering though what ratio of SD ammo should be maintained in relation to practice ammo. I understand that practice ammo would function as SD ammo if things ever got really bad, but I'm trying to come up with some type of plan that maximizes my ammo budget.
