I guess I could be considered a collector in the sense that I prefer to purchase different style firearms, but a shooter in the sense that if I purchase a gun I intend to shoot it, and some firearms I purchased that I wound up not enjoying to shoot as much as others were sold or traded.
For example, I think it's awesome when someone takes one specific caliber and then amasses a collection of firearms chambered in that caliber that yield an entirely different user experience. Like having a bolt-action scoped .22 rifle designed for serious precision, a cheap single-shot .22 rifle with iron sights, a semi-automatic .22 rifle, an AR-based .22 platform, an automatic .22 (if one is so lucky enough to find one), a semi-automatic .22 H-bar/long barreled target pistol, a .22 SA/DA revolver, a .22 SA-only revolver, and a .22 semi-automatic compact pistol.
It's perhaps worth noting that a reason I think that is awesome is related to how my own mind works in a screwy way of taking something similar and pursuing different outcomes. Like some days I get a kick to cook a chicken or a fish, but making several different dishes at the same time to use the same chicken in different ways.
