My collection is mostly hunting long guns - rifles and shotguns.
All forms - rifles are bolt, lever, semi and single shot from .22LR though many different centerfire calibers, "standard", magnum and shotguns, both 12 and 20 gauge - semi, pump, side-by-side, and O/U, even a couple single shots. Mostly field grade, but a few nice higher end examples.
Two 5.56 ARs, one a simple HD carbine, the second a precision build, a tactical shotgun and a few handguns - .22LR target and 9mm and .40 S&W and .38 Special for self defense.
32 slot Liberty safe is full and then a few around and about.
