I have a Remington 870 Express Super Mag 12 gauge, great gun. I also have a Ruger 10/22 .22 lr. The 10/22 is cheap, reliable and accurate. There are also tons of aftermarket items for it. I just bought a Savage 93r17 BSEV .17 HMR. My deer/antelope rifle is a custom made 7mm Mauser.
My dad has a Howa 1500 .223, Remington 870 Express Wingmaster SM, Mossberg .270, custom made 30-06, and a remington .22 of some sort. My grandpa has about a dozen guns that he never shoots. He just sees a gun he likes and buys it.
