I have a 505 Gibbs on a CZ 550 and the bolt face is opened up as far as it will go. So I suspect it would work just fine. I also have a Ruger RSM that started life as a 416 Rigby and was converted to 505 Gibbs so that bolt face worked.I'd love to go with a 404 Jeff but I am afraid I can't make that happen with the rigby bolt face. Would a 505 gibbs work on the action?
I'd sell the action and buy a double.So let's say if you already had a 375 h&h and a 460 wby (built on a cz action) and also had a cz 550 action laying around with the rigby bolt face what would you choose?
It would require opening the bolt and also likely major work on the magazine box. Probably need to remove some metal from the sides under the feed rails so that fat cartridge will hold in place. Mone had to go back to Triple River for work and will only function with brass cases. If shooting nickle plated, they need to be scuffed up with sandpaper or the slip right out.How much extra gunsmithing would it take to convert the action to a 505 gibbs, I am assuming opening the bolt face and some feed rail work. I also imagine a few more crossbolts in the stock and maybe some wrist support
Or the 550 MagnumThat may be a little more work than my wallet can support at the moment without dipping into my buffalo hunt pool. Now that I am looking at the big boys what about the 500 a square
