I’m gonna chime in with a couple options:

Plenty of used Leupy’s out there, if that’s what you want. I’ve got a M8 2.5 on a Henry .45 Colt, and a Vari X III 1.5-5 on a #1 .45-70. Think I gave $135 for the M8 and $150 for the III. While not the brightest scopes, they’ll work as far as you want them to.

Now, I gotta say, Stick’s setup on the Marlin intrigues me. I had seen his setup on another forum some time ago, and, while I’d hate the look, dots and knobs on top of the #1 would afford the ability to land 400 grainers wherever I wanted them, further out than I’d ever need them. As it sits, they’ll kill well beyond the limits of a duplex crosshair and my ability to guess. I think of it as the modern version of a ladder sight on a Sharps.

Someday, I’m gonna try it.
