After you get your sight figured out, you will want to see what range the barrels are regulated at. All my dad's doubles were pretty much at the same impact point at 100 yards. That being a shotgun I'd have to guess it's probably at the most 50 with more than likely 35 yards. I love most of his old doubles, especially the European ones, but there were a couple that would make an elephant drop from the butt end. A mule kick would be a flea bite in comparison. I do like that red neck engineering for your peep. It really cracked the wife up. Said it looks like something I'd do.
