I can only have one?
I guess I'd pick my mossberg 12 gauge pump, since you mentioned hunting and protection together. I could kill a deer, bird, for food with it and it would be very good for protection. I can't kill a quail with my .357 or a .308 and still eat it.
I'd prefer to have all my guns and a truckload of ammunition for each.
I didn't realize that killing and stealing from other innocents was part of the equation when I made my post.240B MG and lots of ammo. Who needs to kill bird at the end of the world when you can eat whatever the **** you want? Ill just kill all those dudes over there with their 12g shotties and take their birds if i really feel like it.
why a 240? because a BMG is too heavy.
(240 is kinda like an M60 for those who dont know)
