1 SCREW OR 2 FOR SCOPE MOUNT SCREWS?

[Jayplace]

Two piece scope rings are offered with either 1 screw or two screws. I would like to use a set that has 1 screw. Would there be any problem on a rifle such as a 30BR?

 

[Geronimo Jim]

Nope

 

[Bill Norris]

Should hold it fine. 30BR don't punch back very much.

 

[Bronsin]

I use 2 just to make sure the mount and the scope stays put.

 

[JMayo]

My 30br has 2, my 6.5mm has one.
Kinda backwards i think !
I would think 1 would work fine.

 

[steve210]

Depends on the weight of the scope I would think

 

[Shooter13]

Also you can use a 2 screw on one ring and 1 screw on the other, that is done lot.

Some guys even do this if weight is not an issue.

the Harrells bases on my BRM have a raised edge on the front to keep them from moving

That is just insurance, because I can.

How about one per side on steel, and two per side on aluminum?

I've used some cheap crap aluminum ring sets for 22 rimfire application before, and I'd never trust a two screw cap on them. Hell, they start stripping at about 12 inch pounds of torque.

Y'all might find this hard to believe, but I've been known to cheap-out on some occasions. jd

 

[FNSafari]

if by two screw you mean 2 screws each side of the scope cap, most refer to them as 4 screw. That would be my choice vs 2 screw, always has been in the IBS score game.

 

[Jayplace]

The reason for my question had to do with trying to move the scope back as far as possible. I have a Leupold Competition 45X scope mounted on a Panda action using the double screw Harrell rings. I would like to move the scope back for a more comfortable eye relief position. The single screw should allow the scope to move rearward slightly, and every bit will help.

Using offset rings helped a little, and I think the single screw will help more. I received a new single screw offset from Harrells. A little bit of nice weather will also help.

When I was referring to one or two screws, it was about the clamping number of screws in each base.

 

[RabbitSlayer]

I have never had a problem with any rings as long as they were a good name brand. 1 screw or 2 all work the same.

I think it depends on a few factors. Most of the time, singles are fine but I had a Stiller Viper in both 30BR and 30 Major that I fought this with for a bit. Those actions are basically a Panda clone but are hard coat anodized. That hard anodizing was tough to grip vs a Panda or other bare aluminum base. The combination of the recoil and scope weight of a NF BR 12-42 was enough on that action to give me fits until I stopped it. Even double screw rings, I had to keep an eye on, so I made a stop on the rear ring that wouldn't allow the scope/rings to slide forward on the integral base. I coulda pinned it but I was a little concerned about it affecting resale value. Absolutely nothing wrong with doing it otherwise.

With a Leupold comp and a set of either combo or double screw rings, I doubt you'll have any problem on most non anodized dovetail bases. Bare vs anodized makes a lot more difference than I woulda thought....fwiw.

I've seen combo rings, but I don't think Harrell's off-set rings come as a combo. I now have both the double and single off-set 30mm rings and have thought about mix and matching rings, but I am under the impression their rings come in matched pairs, so that doesn't work.

I assume that I could mill 1/2 off the lower part of a rear base of a double and have the same thing as a combo. I will try the singles first. Cutting one of Harrell's rings would be a last resort.

Call Harrells. They do combos..or did.

Single screw should hold on leupold 45, anything heavier I would go to 2 screw. Harrells stopped make scope rings awhile back. The new guys running it may have started making them again. Give them a call
