Burris sig. zee rings on 338lm

[pittbull46]

does anybody know if the sig zee rings will work on a 110ba 338lm

[LoneWolf]

I would probably add at least a 3rd ring to be safe. I believe they would hold without issue, but a 3rd ring would provide full confidence.

[pittbull46]

Thanks for the info how would I install a 3rd ring

[LoneWolf]

Put the extra in the sane format as the other 2 right behind the front ring

[yobuck]

I hadnt ever thought about adding a third ring to a scope. Not a bad idea though especially in view of the torquing requirments with some scopes.
My son has a 338x378 with a Vortex scope. At least for the time it takes him to aquire another. The 15 inch pounds reccomended by the manufacturer
dosent hold the scope from moving even with rings with 4 screws each. I believe Burris has 2 screws each.

[LoneWolf]

Yep just add a 3rd or even a forth to increase grip. You'll see this on a lot of serious ELR rigs.

Thanks for the info I will pick a couple sets looking at the sightrons3 8-32x50 with mos to try getting to a mile

[D.ID]

I have heard people claim to have no trouble but.............. After repeated failed attempts even using two full sets (4 rings) at one point.................NO.
Mine was on a 338 edge with brake and there was no way to get signature rings to hold my 6-24x50 more than 80 rounds before slipping.
I switched to weaver brand picitiny tactical six hole rings.

While I really like my Burris Sig Zee rings and the theory behind them, I've often wondered about this issue. D.ID how did you know it slipped? Was it visible or did you notice POI variations?

[stomp442]

Honestly the Burris Sig zee rings would be the only ones I trust.

[LoneWolf]

They actually aren't my first choice. Not enough pro's and high end competitors use them from what I've seen.

[pittbull46]

is there other adjustable rings to get more moa

[LoneWolf]

Not that I've seen like the concept, but they aren't my favorite

[pittbull46]

I think I will give them a try after I get a scope and it warms up a lot thanks for all the info

While I really like my Burris Sig Zee rings and the theory behind them, I've often wondered about this issue. D.ID how did you know it slipped? Was it visible or did you notice POI variations?

Both actually. Subtle POI shifts got me concerned as I was shooting allot and had this gun locked down and dialed in more than any I had owned before so when she started to wonder I was a bit rattled and determined to lock it back down.
The edge or lapua are just to expensive to be re-sighting in all the time.
Marking the scope illustrated the scope actually going back and forth under recoil just enough to move the mark in and out of the edge of the ring and the scope still felt and looked tight.
After numerous attempts to remedy with the signature rings: I doubled up, then tried rosin, then lock-tight in the ring followed by many other recommended fixes before abandoning them for the six hole=extra wide surface "tactical" type rings at which point all my trouble ended and she returned to her former glory.
P.S. the POI shift I was fighting was roughly 1/2 moa at its worst but when a 1/4 moa rifle starts slinging 1/2 moa discrepancies, it's obvious.

Well I have a Badger 40moa base and getting a sightron 8-32x50 with 70 mos adjustment I will oboe be trying a mile shot a couple of times it will take about 65 to 67 mos to get there do you have any suggestions 338lm

[LoneWolf]

What reticle will the scope have? Should be able to hold over the rest of the way.

[pittbull46]

I am going to get the mos reticle

[D.ID]

Bean there. I was trying the sig rings as well for there adjustable moa ability. Assuming your trying to remedy the 5moa high (for a hundred yard zero) issue. Try it first as the math does not always pan out when we stack tolerances in assembly and variables in loads.
The things I could suggest would be:
#1: Shim the base so your almost bottomed out in the scope which also creates a de-facto zero stop, that's what I did.
#2: Accept the 400 yard zero your base and scope will naturally create and shoot.
#3: Switch to a 20moa rail and use your reticle sub-tensions for holdover in combination with your max available adjustment.

[pittbull46]

How did you whim the base and how much
