Hope you Guys can help me out here. I am about to mount a Vari XIII 1.5-5 on my .416 Rem. Mag. using Leupold QR Rings/Bases. I remember reading somewhere, how someone posted that QR Rings are good, as long as they are mounted with the Levers on the correct side so that the recoil does not loosen them. Which side would that be?

Thanx.

That will be on the left side.

I think it would depend on which way the levers operate. You want to recoil to tighten the levers, not work them loose.

Which puts them on the right side if they are Talley QD rings.

I sometimes use Talleys on the right side of a Mauser and time them straight up very snug, or I may cut the rear lever a little short so that it does not interfear with the bolt release and put them on the left side..I always use low bases...

On a M-70 either side suits me. I have little concern about what recoil does to the levers, I snug them down with a 3 inch cheater bar made out of a piece of arrow shaft. don't over do it.

Never had a problem yet. If I ever do then I will let you know. I check them from time to time before I head out of camp.

This question was about Leupold QR, and the levers still goes on the left side

I have a set on my M70,375H&H, mounted by a gunsmith.
Left side mounting will thighten the levers when the gun recoils.

If it has any significant ipmact, I don´t know, but I trust the professional craftsman on this one.

Let me get this straight. You want the levers to be on the right side for a counter clockwise tightening screw and the left for a clockwise tightening screw? Should they be stright up to maximize inertia or just pointing towards the muzzle in either case?

It would depend on weather the levers are postitoned pointing up or pointing down. If they are in line with the muzzle then there would be zero rotational force on the lever.

Weagle

I run the levers on either side, depending on which seems to be less in the way. My Leupold and Warne rings never to loosen, judging by the effort needed to remove them the opposite seems to be true.

Yes, of course.

For levers that tighten clockwise, to get recoil forces to work to keep them tight:

If levers are on the left side of the action, they must simply be set so the end of the lever points in a direction below the parallel to centerline of the bore: levers down

If levers are on the right side of the action: levers up

If they tighten counter-clockwise, this would be reversed.

Simple as that.

Yep, the neutral position for either right or left side levers, whether clockwise or counter-clockwise tightening, would be to have them both pointing toward the muzzle, along a parallel to bore.

But all of this considers only rearward motion of the rifle, the main recoil effect. Let us forget muzzle rise effects as negligible in comparison.

As for the Leupold QR, IIRC, they are meant to be on the left side of the rifle to get the levers to tighten clockwise and point downward, which is well and good, but could get screwed up by having someone just turn each base and ring unit 180-degrees on the rifle: then the levers would be on the right side and pointing downward, and recoil forces would work to loosen them.

Have you factored in the Coriolis effect? Are you going to be shooting North or South of the equator?

Sorry, I couldn't resist.

After I decided muzzle rise effects were negligible, ignoring Coriolis was a no-brainer.
