I’ve always been interested in Martini’s, me being a single-shot sorta guy. To top that off, I’ve always been interested in the .256 Win Mag. An uncle of mine had a Marlin chambered in it & we enjoyed shooting it. The icing on the cake was my rifle came with 200 bullets, 200 cases made from .357 Mag brass, a 100 factory head stamped cases, 50 factory brand new cases & a set of RCBS dies. Looks like it will be a very good cast bullet rig too!

Here’s what I need suggestions on. The barrel is 1.0” dia, straight, no taper from action to muzzle for 20”. This appears to match the dia. of the action face. The barrel is drilled & tapped for a long scope that uses adjustable mounts for windage & elevation. I don't have a Unertl laying around, so I need to get it drilled & tapped with 2 more screws so I can fit a standard bridge or two-piece mount. How do I determine what base(s) to use that match the barrel's straight contour? I have epoxy bedded bases on bench guns before.
TIA for your ideas & suggestions.
