I have this old Mossberg bolt-action 16 gauge that my dad gave me. I used it two years ago when I went hunting but I didn't get to shoot it. I'm confident of it's hunting capabilites because my dad got his best 10 point with it. I was considering getting a new shotgun to hunt with but I wanted to know if anybody still used a 16 gauge? If not, what type of shotgun should I get to hunt deer in Western PA?
