Some pre-64 M-70's were stamped. " 375 MAGNUM " instead of 375 H & H MAGNUM there is a photo of one in the model 70 book.

This was re chambered to 375 AI.

Are the shoulder angles on all AI calibers the same?

I believe so, I think they are 40 degrees

If it’s Ackley & looks like it , I have his books, can copy the sections for you

William, If you're referring to Ackley's HANDBOOK for Shooters and Reloaders, I posted his comments and data. See post #12

Reloading data for this is a moot point as Mills doesn't reload.

My early 25" straight taper .375 H&H Super Grade has "375 Magnum" stamped on the barrel. Could this #10150 be a first year gun? I'm not enough of a Model 70 guy to own Rule's book.

I appreciate all of the advice and honest opinions here. Long story short, the 375 is going down the road and at least one 30 06 is taking its place.

Bill your gun was made in 1937.

It's happened to a lot of us. It was a sign of the times, the Model 70 popularity and wildcatting /improved ballistic attempts if for ever so slight a gain.

One of the true assets of the 375H&H in the original shape/form of the case being that it lends itself to great feed. Same with the 300 H&H.
Good News, unmolested Pre -64, 375 H&H Mdl. 70 are out there, and they aren't as high as they once were.
While I suspect you are wanting a Pre -64 don't totally discount a New Haven produced Model 70 CRF in 375, they aren't bad guns. in fact I think they are better stocked for scope, and they have a gas check on the bolt that sits in the left side slot/rail. Just something to consider.

There is a problem with having a 375 H&H and a 30/06 both set up to suit. The problem being you start running out of excuses of need to buy more. Want never is very far off or long in coming.

I am with Brett on a new Model 70. Much as I like vintage guns Africa trip another thing. Lot invested in the trip best have two of something that works well. 30/06 & 375 can back each other up if one is disabled or lost.

Another factor in Africa don’t take anything you worry about. Chance of damage or theft very high. Smile when customs officer takes your expensive pen better that protest. Advise received my first trip to Nigeria served me well 10 years working all over the continent.

I lost the bolt on a Remington 700 in JBerg. Thief pried the locked case partially open could not get the rifle, airline required bolt removal, bolt must have fallen out. Another African trip pair of Swarovski Binocs stolen from my hand baggage during inspection. Company travel insurance paid me back.

It’s a great place to visit low risk profile best way to travel.

NEVER!!!

If all goes according to plan, I will trade the current 375 up to a real one. Then I have some Remington semi-autos which will likely go down the road for more M70s. My son Harry wants a 308

In a pre 64 M70 the fast majority of 308's were made in the FWT configuration as were the 243. To find a STD grade 308 will be difficult and expensive. I do know where a nice 308 FWT is if your interested.

If your considering a 30-06 the 308 is redundant and visa versa. With the proper bullet and it's placement there isn't an animal that can tell the difference. I prefer the 308 over the 06.

I am a big fan of the 7/08. In a Winchester same ballistic advantages in the 270 lot of M70 270s out there . Having said that sold all my CF Bolt guns except a M1903 30/06 arsenal built sporter and a 721 Remington .222. The 03 is accurate and absolutely reliable. 721 accurate and finicky feeder

This may have been brought up earlier in this thread.

I don't recall if you may have mentioned having it or not, but if you don't, I think you'd be served by obtaining a copy of The Rifleman's Rifle by Roger G. Rule. Think of it as the TPS for the Winchester Model 70 1936-1963.

Yes. That book is on my list

Good books essential when buying
