Howdy Silver Creek Slim,
I have one of those rifles, from that era. I put a Leupold scope on it for a while. It would shoot groups into 1" @ 100 yards, benched-off sandbags, using the scope and factory Remington 405 soft points. Wish I could say I could do that with iron sights<G>. I tried black powder loads with lead bullets that I used in my Trapdoor, but it would lead up the barrel after about three shots. If I were to try lead bullets again, I would use ones from Laser-Cast that are much harder than those I experimented with. I hope you end up liking your rifle as much as I like mine.
