Hey everyone!

This is my first post here at the forum. I've been lurking for a while, reading as much as I can about doubles, but have finally reached a point where I need some input and advice.

After having just completed a fully custom 375 Taylor bolt rifle, I am now moving on to a much bigger undertaking. Basically I am looking at building a "poor man's double", using a Lanber "Supreme" spanish SxS 12 gauge shotgun as the action. It fires 3" shells, and is of fairly new vintage, ie no damascus barrels or such.

That being said, I have no real idea whether or not this is a decent action to use. I am way out of my lane when it comes to double rifles and "proof marks" and "boxlocks" etc, as I am more of a bolt rifle guy. So this is where I could use you members' input and advice. And I have a thick skin, so if anything I am doing is crazy or rediculous, by all means, let me know.

Basically my plan is to either insert a set of sleeves into the shotgun, or rig up my own monoblock, depending on what opinions and advice I get here. I don't have a caliber picked yet, as I don't know what kind of pressures my action will be able to handle. That being said, I am not adverse to the "low pressure-big calibre" route. My goal would be to have anything from a 400-600gr bullet at speeds around 2000fps.

Below are pictures of the action, as well as the markings on the action. The face (I think that is what it's called) of the action measures 2 1/4" or 6.8cm across.

Please let me hear any thoughts/opinions/rants, as I am very much a rookie when it comes to this aspect. That being said, I have read a bit, as well as thumbed through "Building Double Rifles on Shotgun Actions", so I do have a very basic grasp of the concepts. Thanks very much -Cameron
