The 404 Jeffery

[Michael Dean]

I currently have a 375 H&H and I'm thinking of having it rebarreled to a 404 Jeffery. Can someone please tell me if this is going to require a new bolt face?

What brand/model?

Maybe. The 404 has a radius .009" larger than the standard magnum. The boltface may need to be milled out to accommodate the larger case and the extractor will likely need some fitting. Unless it's a Remington style bolt it isn't much of a problem.

What brand/model?

The rifle is a Colt Sauer.

Michael, don't be surprised to find feeding issues as well.

The rifle is a Colt Sauer.

Oh I've no experience with that rifle. However I'm pretty sure any 375 bolt face would need to be opened up a little. And I'm almost positive that it can be done.

So a new bolt face? Not sure what your definition is. Your old bolt face, machined out just a bit should work.
