If you would like an extra round in your "Classic" M-]70 magnums..here's an easy retrofit.

Capacity has been increased by one round through the design of a new stainless steel magazine box. Stock depth remains the same and there is no modification to the action.

Throw away the magazine spring that has a "loop" at the bottom and replace it with a standard spring. You can use your original follower or replace it with a machined stainless follower.

Steve can you PM me details please for box and follower (and spring if you have one) for a Classic 375H&H? Can't find any info on the website.

Best wishes, Chris

Steve,

are you saying to buy the new ss box from duane as well as get a new follower from duane and get a standard spring from him as well and voila a 3+1 M70 classic becomes a 4+1?

This looks and sounds like a great idea!

I have two questions, first what is the total bottom line, (everything included) cost of this modification. Parts, polishing, bluing, labor- broken down as much as possible.

And second - seeing this, I have to wonder why Winchester does not build the guns like this up front. Would it cost more, or is there some other trade off involved?

ditto for me

The main question seems to be cost. The box is $47.50 follower $49.50 spring $27.00 for a total of $124.00. You DO NOT need to do anything to the action. You will need to open up the stock for the new box. You should not need to blue anything. The box is SS.

jsl3170 YES!

Fourbore, I guess Winchester did not think of it. Duane tried to ask them if they would be interested and they seemed not to be.

At Duane's request, I have posted photos of the magazine boxes in the Gunsmithing forum.

Holland and Holland got this right in 1912. My 1913 H&H 375H&H takes 4 down, but the extractor has not been modified to slip over one not loaded from the magazine, and I'm not going to do it either!

The H&H box is about 2mm (0.08") wider than a Mod70 Classic SE 375H&H, but a fraction shallower.

Cheers, Chris

For a dangerous game rifle..or for any Mauser, I always make sure you can single load. If you get one ahead of the extractor, you'll need a cleaning rod to get back into action.

It's a pretty simple modification, the "bite" is not decreased at all.

And...thanks for the info..

Duane, the mod to the extractor is no big deal like you said, but you can use an old German Army fix to get back in action without a cleaning rod. I am listing this here as a public service to the masses.

If you get a round ahead of the extractor you cradle the rifle with your legs / crook of your arm and use two or three fingers putting pressure on the rear section of the extractor, depressing the spring and retracting the hook while closing the bolt.

OK I thought you had to get the whole bottom metal. That is a good mod for the not to rediculous price. Can I get a PM on the price to mod the extractor? And possibly install of above said components?

Thanks!

Sorry, my comment re the Mag Mauser H&H seems to have taken a bit of a life of it's own!

gunslinger55 the Mod70 extractor will close over a singly loaded cartridge without requiring any modification.

My apologies for the confusion.

Will be putting my order into Steve today, these look great.

Best wishes, Chris

Rocdoc yeah they close, just tears up the rim a little.

What about the mauser interams? Haven't tried it yet

Airgun...that works! MOST of the time

Yes, all I have owned (8-9) close on a chambered round.

Gunslinger 55: Way back, Winchester was using a relatively soft extractor material that failed often...they then went to a brazed on tougher hook...One mickey mouse fix after another!

A new Wisner extractor is the permanent fix and when properly fitted, should not tear up the rim

Just went to wisners sight and apparently they discontinued post 64 claw extractors? Will a pre 64 extractor fit my "classic" 70?

Thanks

Yes

gunslinger55. The Williams replacement Classic Mod 70 extractors are supposed to be the best (only?) replacement. I bought a couple but haven't installed them yet. Anyone using them?

Not sure what the extractors are like on the new Mod 70's.

Cheers, Chris

Thanks for the info. Where did you buy the extractors?

gunslinger55 I bought mine in Aus. However, I just checked Williams website and don't appear to be able to buy them? Was redirected to brownell's and they didn't show up!

Perhaps someone else can advise on their availability. Not sure if the current ones are any different to the Classic ones.

Cheers, Chris

How much opening up of the stock in the mag box area is needed?

You can push the fourth round down on top of the other three about half way and move the bolt forward. The extractor will smoothly pick up the rim and flawlessly feed the fourth round into the chamber. No stress on the extractor at all.

So, by buying the new box, the follower and spring you're in for approx $125. Can you use the factory bottom metal? If you want an in the bow release will the Williams work? Can anyone answer Fjold's question, too?

Does this new magazine fit or adapted to a pre-64 action?

At the front of the magazine well..about .055 per side..nothing at the back, so it's sort of a "taper"..this is only towards the lower stock line..it's the shape of a trapezoid from the front view..at back it's sill a rectangle.

No...we made it only for the classic. Depending on your access to tools, you could modify the old box, I suppose

The box is designed to use factory bottom metal. I suppose the box could be shortened vertically to fit frame type aftermarket bottom metal...I'll get feedback from Rockdoc shortly

Thank you, Duane.

Sorry about the delay. My gunmaker received the box, spring and follower last Friday thanks Duane, but hasn't had much time to take photos etc.

The new box is as follows:

Compared to standard M70 Classic 375H&H box, the SMP box is 4mm wider at the front and 0.5mm wider at the rear. All other dimensions are the same.

It fits well in my D'Arcy Echols Legend stock. But not in another (diff spec?) Legend stock. Mine was ordered for a Echols box, which is wider than standard.

The box needs to be shortened (ie in height) to fit Duane's 2W bottom metal. It has to sit on top of the bottom metal, but that should work fine.

Will report more, hopefully with some photos, soon.

Best wishes, Chris

Interesting idea and one I may pursue. Hoping that I can get 3, possibly 4, down, as well as reliable feeding on a M70 Classic rebarreled to .416 Ruger.

Just a heads up! I'm sure understood by most (but not all) that a new magazine box will not CURE feeding problems

Understood Duane but will it cause any?
