Just bought this gun

I want to scope it.

Question 1) leave the receiver holes #6 or change to 8-40’s?

Pending answer to 1)...

Question 2) what mounts would y’all recommend?

Gonna take it hunting in Africa.

NO you do not alter this original piece in any way. Unless you want to instantly reduce the value.
Use a one piece Leopold base.

Had some heavy kickers over the years, still have a couple. All with #6s securing the base/bases. Never sheared/broke a one.

+1

I would really like to use QRW2 rings on it. I would like a one piece mount for sure...esp due to the #6 screws. Does Leupold or anyone make a cross-slot/Weaver type one piece base that would fit that action? I wonder if Leupold custom shop would make one for me?

it wont be as classic as a leupold base, but you can get a piticanny rail for it.... then use the leupold QRW rings on it... sacrilege , I know, but functional...

Easy for you to mill out a one piece Weaver/Picatinny rail for it. I am sure Leopold won't make just one. Just get a new one and re-drill the rear hole.

How about Talley bases and rings? I have them on my pre 64 .300 H&H and they look good.

Who makes a once-piece steel picatinny rail for it?

Wonder what the rear hole-spacing is on the Warne M676M? Wish they would put that stuff in there web description.

I have them on my old .300 H&H too. And I do like them.

That said...I did break a #6 screw in the front base of my 1957 .458...during a hunt. That is why I am being more cautious this time and like the idea of a one piece base.

Dunno...I guess I’m a heretic. Make the thing like you want it and enjoy it. You may take it to Africa, fall, and break the stock. Then where did all the worry get you?

If it’s that important to keep it pristine, put it in a box and shove it under the bed. If anyone disagrees, they can buy it and do it.

Above all else, have fun

Tom,
Will you make me one if I can't find one?

Lane, it looks like Brownells carries a number of one piece picatinny base/rails for the model 70. The only downside, imo, is that they might be a bit slower to reload as the one piece base covers a portion of space between the scope and the loading of the magazine. Not real important in a deer rifle but just might be in a DG rifle.

Good luck. Nice snag on a great rifle.

It could be milled out a bit like some of the Warne one rails couldn't it?

Will look at Brownells...Thank you.

Just spoke with Leupold, Warne, and Brownells support. Nobody makes a one piece Weaver/picatinny rail to fit that action.

Don't mess with the gun!
Just have a recoil lug added to the base. Front or rear. Use the original screws.

Lane, sorry about that. It sure looked like there were a couple of options. I just did a quick google search for pre 64 long action bases and both EGW and Nightforce appeared to have one piece picatinny style bases. Please see if that works for you. You would definitely want one with 0 MOA. Good luck.

Leave it alone and enjoy it the way it is. If scope is mandatory... one of the old Redfield 1-piece base and matching rings. Think I have one with a flip-up peep sight, and engraved rings.

Phil

On the e place look for a Winchester model 70 pitching rail.. Several are there for less than $50.. Talley plo 252702 for $47.72.. Leopold backcountry cross slot 171342.. So they're out there..

Not pitching rail... Pitcanny..Spell Check

Leupold Back Country doesn't make one to match that rifle.

Brownnells looked up the EGW and they have one for new ones but not for the old with rear .440 hole spacing.

Will look at Night force.

I would be interested in seeing what that mount looked like.

Will see if I can get you some photos of it in a little while.

Phil

Yes I will make you one. No one will make a Picatinny rail for such a rare rifle. The demand would be, zero until today, then one, then back to zero.

This is a Warne Mauser 98 mount.

Would it be possible to make something similar with the milled loading section but with both holes in rear section?

I don't think the 375 H&H kicks enough to worry about.

I've shot my Model 70 375s quite a bit with never a problem.

But hey, it's your rifle so do what you want.

yes

Hi Tom,
I will PM you.

In my book without exception there is only one way to mount bases and that is to use an epoxy (two tube) glue on the base and screw threads. The epoxy takes the shear strain and also prevents water, blood or any other gunge getting under the base to cause rust and corrosion. Epoxy breaks away with a little heat applied to the base and screw heads and brushes off easily using heat to soften the glue without damaging the bluing.

Some question the need for using glue, I've never had to question the integrity of the many bases I've mounted over the decades of my life messing with guns, mine and many others.

If you want a classic look keep your eyes open for a used Buehler 1 piece base and rings. I have had one on my .300 H&H for ever.
C.G.B.

6-48 screws are just fine. I would glue the bases to the receiver as well and I would use steel Weaver bases and QRW's. Regards, Bill

I 8x40-ed mine (no collector value worries) AND glued it on with J-B Weld,
with 2-piece steel cross-slot bases, either Leupold QRW, Warne Maxima, or Burris X-Tac.
I could not find a one-piece Pre-'64 M70 H&H Picatinny base either.





Since then I am dabbling in custom Picatinny bases, starting with a CZ 550 Magnum which is easy since it is a flattop/square-bridge action.

Here is an example of the recoil stop that abutts the rear of the front receiver ring:



You would want something like that if you leave the screws 6x48 and not glued.
I would accept 6x48 screws WITH epoxy, not without.

Ron,
Have you ever taken off a mount JB Welded on?

Eagle 27,
An epoxy like Accraglass?

Don't worry; any of those adhesives will turn to powder with a little heat.

Problem solved; EGW makes the exact base you want, and it uses 6-48 screws. For pre 64 Winchesters, with the 375 hole spacing.

Ordered today!

Thank you kindly Tom!

No, thank you for saving me a lot of work.

Yes, many times. The heat resistance of J-B Weld is greatly exaggerated but the strength of its bond is not.

The action shown above has a .395 H&H McGowen barrel on it.
Before that it had a .375 H&H Douglas barrel.
Originally It had a Winchester .300 H&H barrel.
To re-barrel to .395 H&H I had to remove both bases previously J-B-ed on with 8x40 screws.
Those were the old-style Kimber QD-lever bases.

Take barreled action out of stock.
Wrap it with dripping wet shop towels.
Position it in a rubber-jawed vise with scope base exposed upward and level.
Apply propane torch flame focused cone to one screw head at a time until it loosens, usually quite easily.
Do next screw.
By this time the base is usually off or just needs a little tap to fall off.
Bronze/brass bristle brush or 0000 fine steel wool removes any adherent epoxy, no damage to blue.

I will have to get one of those aluminum Picatinny rails from EGW and give it a try.
Appreciate the finding by dpcd.

As stated in the testimonials in the ad, my current 2-piece Leupold QRW is limited to long scope mounting length.
The Picatinny will allow you to mount anything, short or long.
I would prefer a custom Double-Seyfried-Schtick 2-Piece Picatinny (DSS-2PP) of stainless steel from Bubba Gunwerkes.
I need to get with R&D on that.
The EGW Pre-'64 M70 H&H base could serve as a template for something like done for the CZ.
There is J-B Weld dripping out all over on this one:


(As previously seen on THE .458 WIN MISSION thread of Big Bores forum.)

Rip ...
