Shooting them will not wear them out.
Use only light loads, even in repro Parkers.
As I am learning, heavier really doesn’t mean any better to break a clay.

Now you’re digging where the taters are! For 12g, keep the loads 1 oz or less and ideally around the 1150-1180 FPS range and you’ll have soft shooting and a scoresheet full of XX!!
