Wait what!?!?! Of my two competition shotguns for 3-gun (Benelli M2 for Tac Ops and a Stoeger P3000 pump for Heavy), neither one of them really needs any attention for many many hundreds of rounds or more. No joke or embellishment at all here but my M2 has close to 25k rounds on it and has only been cleaned at most maybe 6-8 times ever. My P3000 is much newer and has only seen a few seasons of competition so the round count is much lower but I actually haven't taken it apart and cleaned it since putting it into service. It has been used in 2 or 3 dozen competitions since then, many of them being 150-200 rounds each. If you can't get more than 30-40 rounds out of a gun then there are some other problems going on there.
my bad… my competition guns are 125 years old and shoot black powder.
