Having shot a lot of clays & live birds with LW (alloy) K80 & K32 it seems to me that the alloy guns do exhibit a bit more wear than same steel gun would. That said, I have a SLF 16ga I hunt a lot and also shoot a few pre-season clays. Other than handling marks,it shows no significant signs of wear. The SLF is really too light for serious (100 round +/-) days of clays shooting in any event.

A Springer Spaniel, a 6# double and a fair day to hunt.
