Good Mourning: I have 4 CZ550 Magnum actions,3 have 416Rigby bolt faces and 1 for the 375HH.Can you weld and remachine the bolt face of the 416Rigby to accept a smaller rim size? If so,would it be cost effective? Thank You Paul K

There are ways to alter a bolt face to accept smaller case head/rim diameters. But today, I have no idea what aa qualified gunsmith would charge for such an alteration. It might be cheaper to but a new bolt body!
I have seen it done on Mauser bolt faces. I believe the operator used a TIG welder to control the heat. Personally, I don't like the idea. I think that I would be wondering every time I pulled the trigger.

"Ring" it by epoxying a stell ring inside and then turning to correct size for the base of cartridge.
Greg Tannel's excellent tapes cover this procedure.

ANYTHING can be done and done properly if you can afford the price, including changing a bolt face and much, much more....In this case it could be tiged, recut, softened and rehardened by a good gunsmith or cut in half and tigged back together with another bolt face, but why? a new replacement bolt would cost much less...

eldeguello and ezell: Thank you for your input.My predicament is that I already have 3 416 Rigby's and most likly another Ruger 416 Rigby on the way.I bought the one action with the intent to build a 416Rigby but now don't see the need.I really want a 404 Jeffry a 375HH and a 450 Rigby.The 404 was the reason for getting the bolt face welded and recut but I never thought about the heat affecting the bolt.Thanks again for the input.

I second what Allen says but in spades! That is an absolute NO-No!

This can be done relatively easily and safely by carefull bead on bead tig welding with the proper rod, followed by turning a new rim, recutting the ejector slot and then very importantly re-heat treating and tempering. Now you get to play with the extractor. That's about a $200 job IMHO. I once built a 6ppc on a mauser action and used this approach. It does work,however, I'd personally look hard for a new bolt first!-Rob
