Hunters don't. Shooters, however, should. I suppose it depends on how little volume someone feels happy with to call themselves a shooter. I can't feel too good about shooting even a 308win less than 4,000rnds in a decade. But in fairness, most firearm owners are exactly that - the firearm leaves the store, finds a closet to hide in or bed to hide under, and only see a range a few times a year the rest of the owner's life, if that. I recall my HS girlfriend's gpa who fancied himself a shooter, he had a 22LR pumper and a Win 70 pre-64, like my brother's, which he bought 10 boxes of ammo with when he bought it when he got back from the war, and remained 3 boxes left when he died 50 some odd years later. That wasn't how I defined a "shooter" for myself then, or now.
