I just bought a second gun safe to house the muzzleloaders that were sitting in boxes and gun cases around the room. In time if I need to get another safe, I will. I could not possibly sell any of them. I am a gun owner, not a trader ar salesman. I just hope they all go to a good home and are well taken care of when I go. My very first Inline that I purchased is a Brolin Arms plunger style .50 caliber. I haven't shot it since I harvested a deer with it about 3 years ago. But you know what? I'm dying to get it out and try some of the new bullets and sabots I just got. The gun only cost me $90.00 brand new. I love the gun and the memories it holds and I could not, nor would not ever part with it.
And besides, overkill to me is shooting a 60 pound doe with a 555 grain maxi ball from a .58 cal. muzzleloader, and has nothing to do with how many guns you have.
