I just installed a Leupold Vari X-III 1.75-6EX32 scope on a new Model 70 375H&H using Leupold QR mounts.

QR mount: 50063
Rings: 49971

Now I notice that case ejection is being inhibited by the rear mount. Leupold says they haven't heard of a single instance of that on a Mod 70.

Instead of cases flying out the port, they CLANG, and then usually go just a couple of inches. On one occasion, the case bounced off the rear mount and fell back into the action!
(Wouldn't that be fun on a DG encounter?)

Here are a couple of pictures...

Anybody else know of a problem like this?

One suggestion was to grind off a corner of the rear mount.

Thanks,
Rick.

Something isn't right.

I have the same mounts and gun( except in 416) and haven't had any problem. Check the extractor for any burrs and that it has a good grip on the brass. It may be letting go of the brass too soon.

Does it do it regardless of how hard or fast you work the bolt?

Several others here have the same gun and mount set-up so maybe someone can help.

Good luck and keep us informed of what you find out, Joe.

Get rid of that extension rear mount, and put the rear scope ring to the rear, above the bridge, where it belongs. This will also give you more room when loading the magazine.

I would say to use an extension base in the front and a standard base in the rear, or both standard bases. The extension base in front would let you move your scope back, which I'm sure it needs anyway. This should solve the ejection problems. You could try to trade the bases for the proper ones wherever you bought them.

It looks like you have a problem with a loaded case?!?!? Does it do it with fired cases?

I have Tally rings on my M70 .375 and no problems.

Check the photos guys, he does not need an extension base, the scope has a long tube. The extreme protrusion of the rear extension base is causing the problem, remember, this is a M70 375 H&H that has the front of the rear bridge machined about 3/8" more to the rear to allow sufficient room for the longer case, and loaded cartridge, to eject. Take the extension base out of the equation and the rifle will work as designed.

I use Talley mounts, no problems.

I have the same rifle (but 416 Rem) same QR bases and 2,5-8 scope and have no ejection problems.

Thanks, guys, for the help.

Sometimes it ejects properly, sometimes it just falls out. At high speed, it's hard to see, but the noise and small dents tell me it's fighting its way out of there. A fired case seems to eject more smoothly - I think the added weight keeps the case down lower.

Ken - you're right. I do need a little more rearward travel for the scope.

I think I'll try Talley mounts.

Are those "Quick-Detach" style mounts & rings?

I see that Midsouth and D&R Sports don't advertise Talley mounts - any recommended sources? (Ooops - I just found the Talley website.)

Thanks,
Rick.

Things aren't going so good here.

I just talked with Bear Basin Outfitters, and they looked at the picture & said that's the way it's supposed to mount.

Unfortunately, the rings are now "used" (I still haven't fired this gun), and they can't take them back.

So now I have a choice:

1. Throw away the $60 and buy new Talley rings/bases for $125, and "hope" it's better.
Since other folks are using the Leupold bases with no problem, I am concerned that this rifle may be just as "unique" with Talley bases. Then I'm out another $125 without a solution.

2, Introduce the rear base to the grinder, and just live with stretching my neck a little to get to the proper eye relief.

Rick.

Request:

Could somebody with a post-64 Model 70 in 375H&H and Talley bases & rings take a picture from the side and post it?

I'd certainly appreciate it.

Rick.

Rick, I've got the 1.76x6E on my M70 .375 in talley rings and bases. Unfortunately I don't have a digital camera to take any pictures but I can tell you that there is no overhang of the base on the rear of the ejection port like there is with the leupold QR's (I had them on another M70 .375) I've got my scope set in the rings where there's about 1/4" travel from the front ring to the bell, and 1/4" from the rear ring to the power selector ring, so if you went from one extreme to another you'd have about 1/2" eye relief adjustment. Mine just happens to be correct for me with the scope centered in the rings.

I never had any problem out of the leupold QR setup but I didn't like the base overhanging the ejection port, it restricted access to it too much. Mine ejected empty cases just fine and loaded rounds okay too, but I didn't do a "full force" ejection when running my loaded rounds through the rifle so I can't say for sure whether mine would have done the same thing as yours had I really cranked them out.

I prefer the talley's because you get full access to the loading/ejection port. I don't like the overhanging base on a dangerous game rifle because it might inhibit reloading or clearing a jam. I've never noticed the point of impact shifting with either the leupold's or the talley's.

Hey Rick, I will post a photo, I have 4 M70's in the shop now that are the extra long action (with the machined out rear bridge) and the 0.330" hole spacing for the rear mount. I will take a photo in the morning and post, two of them have Talley rings & bases. The Talley's do not hang over the magazine as your base does.

The problem with your setup is the rear extension base is for a normal M70 that does not have the short rear bridge. The extreme overhang is getting in the way of the cartridge, as the bolt goes back further that a normal M70, the bolt stop and ejector are shorter. Thus the interference.

Talley mounts are about the best for repeatability also, and are easier to take off and put back on than the Leupold with the post on the bottom of the rings.

John Ricks, does Talley make a lower version than that?

Don't forget the objective bell, if you have a regular scope the rings shown may be too low and the bell will touch the barrel. Rings shown are "low". This rifle also has a 3-1/2x10 Vari X III, it takes "high" mounts for the bell to clear the barrel, has about 1/8" gap.

Boltman, John,

Thanks for your help. It looks like I need a set of Talleys. Maybe somebody on Ebay needs a new set of Leupold QR mounts...

Rick.
