I have an old Lefever, damascus barrels that I am restoring myself. I have been thinking about a double rifle. Not for dangerous game, mainly deer, etc.

I also have a set of 12 gauge 18" inserts for 45-70 from MCA Sports http://www.mcace.com/shotguninserts.htm

My question is this. Will the Lefever handle the back pressure from a 45-70? I know there are other issues, such as extraction and regulation, but before I go any further, I thought I would ask.

Thanks,

Pete
