Skeet averages define the inefficiency of the .410. A fragile close target and it can’t keep up.
Of course Wayne Mayes ran 200 .410 100 birds straights with the .410. However, out of 1000xXXXX rounds to keep it in perspective. Few will ever equal it. Which more or less proves the .410 on flying game is something best left to very accomplished shotgunners. Kids starting out?
