You just an old fuddy duddy. If you gonna blow something up, I'm your huckleberry. About your shooting. I live in heavily populated NY. I step out into my back yard and shoot shotgun and hand gun without pause as neither of them has the range to carry. I do make sure of my back stop when I am firing rifle though.
I sold a revolver that I bought 62 years ago to a local gun shop. Is that a possibility for your stuff?
