My uncle left me a Mauser Custom 375 Chatfield-Taylor. The only markings on the rifle say 375-338. There are no other markings anywhere on this rifle. No serial number nothing. His printed record is where it says it's a Taylor. But I have nothing other than that printed record. Would there be a serial number under the stock?

What a beautiful rifle!
I have no experience with the cartridge, have just read about it over the years. I believe it's merely the 338 Win Mag necked up to 375, but I could be wrong. There is handloading data available for it. It doesn't give up much to the 375 H&H in power. Should be easy to come up with mild loads for plinking, target shooting, and deer sized animals as well as loads for big, sturdy game...
You could have a gunsmith check the chamber for you and determine the exact dimensions, to verify that it's chambered for 338 necked up to 375.
There might be a serial number visible if you remove the stock - which is easy to do. Very interested in how this all shakes out. Cool old rifle, and I'd think well worthwhile to investigating.
And welcome to the Nosler forum!
Regards, Guy

375-338 WINCHESTER MAGNUM - Cartridge Collector
The specimen above was made in South Africa by OPM. It has a shorter neck than the Quality Cartridge version Also known as the 375/338 Chatfield-Taylor or the 375/338 Belted Newton. It was developed by RF Chatfield-Taylor of .416 Taylor fame, another great wildcat calibre. This wildcatting thing...

As Guy already said, welcome to the forum AND what a beautiful rifle!! Someone put a lot of quality time and effort into its construction!
I have one and used the 4350 data from P.O. Ackley's book. Rifle is a tang safety Ruger M77 with 22" barrel. It's in a Ramline stock at present and total weight loaded with scope and sling is bout 7.5 pounds. I've named it, "The Hammer" because it hits like a hammer at both ends.
