RE: Addition to the battery.
I think if you ever get a big gun, like a 45-70, you won't be able to stop, and you'll be getting a BAR Safari in .338 next, and a 300 RUM, and who knows what else. I think a 45-70 wouldn't be a bad idea, you could get an H&R Handi-Rifle, they come with open-sights. If you add a limbsaver recoil pad, you'll be set.
