Currently available way to get a 4 round magazine Winchester 70 375 H&H

[Ontario Hunter]

Well, I misstated the obvious: If we are talking about Oberndorf bottom metal, then I assumed (we know how that goes), that a reader would understand the mechanism, with the hinged floorplate that opens and swings down.

The point is Pre-64 use an integral magazine box, properly dimensioned for the cartridge(s), and the feed rails of the action correspondently dimensioned for proper feeding (a la M98).
Post 1994 Classics use a separate magazine box, that dimensions determine the feeding for the cartridge(s).

Interesting about the NECG Magnum follower and trimming to work with .404 Jeffery.
I bought one for an Interarms Whitworth .375 H&H, that was not feeding properly. That and a new magazine spring, problem solved.

I tried several places to find a follower spring that was not tapered at the end like military Mausers. No luck. NECG used to sell magnum springs but no longer when I needed one. I seem to recall Hoosier or Midway also listed them but out of stock. My follower from NECG would have been a good fit for magnum Mauser action but lengthwise a tight fit in my standard action build for 404. The very slight trimming to follower side tab(s) was mostly to fix occasional hangup where mag box meets receiver. Mostly, as I recall, it involved beveling the square edges of tabs.

I have the Sunnyhill extended bottom metal on my 'Classic' M70 .375 H&H rifle. It holds 4 down and works just fine. I had a custom stock made so that it fit properly. It is designed to use the standard magazine that came with the rifle.

Here is a photo prior to final stock finishing...

I have read about the Duane Weibe XRM magazine box that was available for the Winchester 70 in 375 H&H. Unfortunately, it does not seem to be available anymore. Is there anyway that is currently available to increase the magazine capacity? I read something about changing the magazine spring to one without a hump using Winchester P/N U356420930 Magazine Spring L/A; does that work? It really seems a shame that the XRM stopped being available.

Interestingly, my gramps 1965 produced Winchester 70 375 h&h, the first of the push feeds, (completely stock as far as I can tell, with no drop box mag) holds 5 rounds below a shut bolt in the magazine and cycles well. Idk what they did to accomplish this in a flush magazine. I was surprised to learn this the first time I fully loaded it.

My Pre-64 Winchester 375 H&H has a Sunny Hill and it’s holds five, almost six, in the magazine.
So with one in the chamber a full six rounds of 375 H&H is a lot of hate and discontent to throw down range!

I wonder what is different between the post 64 rifle you mention and the newer Classic rifles. Did Winchester change the magazine box or is there some other significant change? 5 round of 375 H&H below a closed bolt is way different than 3 in the newer rifle.

Why? If the perfect DG gun is a double, why would need or want more than two?

Probably because sometimes 2 isn’t enough.

I’m curious about this, my post 64 M70 didn’t have any bottom metal or hinge
Just 3 +1 and wooden bottom
I wonder if Winchester was playing around for a couple years after re tooling?

Interesting. I've never seen a factory M70 with a bland magazine.

Jim Brockman, http://www.brockmansrifles.com/index.php has made a few extended Model 70 magazine floor plates for me.

This is very very interesting because it looks like a simple floorplate change and no restock. Most of the items posted in this thread, like the extender sunny hill, require a restock.

Offers a very nice looking similar product for Rugers. Unfortunately, I have messaged them several times asking if they would do the same for an M70, with no response.

This seems like a low cost, easy solution.
