If its true that is that strong its a shame that almost everyone thats been rebuilt here around ends at 8x57r.
I was initially wanting to build something to shoot 9,3mm bullets (and will so do also) with the intention to build a ,375 if the 9,3 works well(and if I'm capable of it). Thats why i'm interest to here from anyone that alredy rebuild one to know how much force it can live with.
But if it can hold it why not a 450NE 3,5"
Gentlemen, as I understand it, the donor shotgun action, for this project, is a 12 ga! If so, the action is, IMO, too big for the .450s,though it could be done. I would go for the 500NE. Then use NFB loads, and work up,to a load that shot well in both barrels for group, without pressure sign, before regulating, then regulate for that load.
The Merkel action will take a lot of pressure above that chambering, which is quite mild in chamber pressure. The limiting factor here is, the shotgun wood work was not designed to take recoil heavier than the 12 ga shotgun recoil. Some work might be needed here!
The 375H&H,416Jefery,470NE, and 500NE Merkel double rifles are built on a 20 ga size action! The 12 ga is much wider, and is better barreled to 470NE,500NE range of chamberings, as the 500NE Merkel is a little light in the factory rifle, built on the smaller action.
