OK, my next gun for preps is a 12ga. I was thinking along the lines of THIS. Not thrilled with spending all that, but at the same time, I want all those features. I know I can get a stripped down version then upgrade later, but let's face it, I never will. I'd rather get what I want now, right? Suggestions or comments on the gun? Next is ammo. I know nothing of shotguns or ammo. What is good ammo for home defense? I'm not a hunter, but will be learning soon, I hope. What ammo for hunting? Deer? Small Game? Are there different barrels for different shells or slugs? What is choking? I think it means tightening the spray pattern of the shot, right? Does every gun have that ability? Should I look for that in a gun? Sorry to throw all those questions at once, but when you go to the doctors, you get it all out so you don't have to come back. Thanks in advance to all.
