I agree with skeeter - a Leupold M8 4X Compact has an eye relief of over 4" . I have one on a Ruger No. 1 .45/70, in which I shoot some loads giving 55 ft/lb of recoil, and the scope hasn' t hit me yet. It is the butt of the stock which does the damage.... (har har).

I think those folks who put astronomical observatory variables on muzzleloaders are just comical as hell.....[&:][&:]
