I can have a ton of fun with a .22lr. And I can have fun all day every day with it AND afford it.
Semi auto fun? Penetration tests with a .357Sig... WHEW!
Revolver fun? Hard to beat anything that ends in Magnum; unless of course it ends in "Colt".
Rifle fun, .223 or 7.62x54r.
And anything black powder is a Blast
, including black powder itself.
