More than 20MOA base? Anyone?

[upSLIDEdown]

So I recently went to an ELR (Extreme Long Range) shoot with some friends and there were a lot of Remmys, seemed like there was a lot of talk of 100 moa bases. Does anyone make a base like that for a Savage? I feel like they all seem to be 0 or 20 moa...

Most I think I've seen is a 40 moa from Ken Farrell. Anything else out there?

[LoneWolf]

Not sure what cartridge their shooting that would be able to take advantage of a 100MOA base, but if one really wanted they could do the 40MOA Ken Farrell base plus Sig Zee Rings with an additional 20MOA for a total of 60MOA. If they need that much additional elevation they are either shooting extremely far, need to get an optic with more internal adjustment, or upgrade the cartridge they are using.

Even Shawn Carlock of Defensive Edge using his Custom LRKM rifle chambered in his own 338 Edge +P required like 91.5 MOA on the scope (NightForce NXS) plus 10MOA on the reticle to make a shot on the side of a mountain (maybe 8' x 8' wall) at 2751yds. I don't see those guys doing much more than that and calling it an ELR shoot.

They must be trying to shoot a .308 to a mile or something.

[upSLIDEdown]

Hah, no .308s. These were all big boy guns. Custom actions, etc.

Smallest thing there was a 338LM. A few others were 338 Allen Magnum, 375 Cheytac, 408 Cheytac, 375 Snipetac, etc. Starting at 2000 yds and moving out to 3600. So yeah, ELR. Most of them were running 40 moa and 60 moa bases curently. Just trying to see what's out there for Savages. Think I'm getting ready to build a 338 Edge for a budget way to get my feet wet. We'll see how it goes.

[sharpshooter]

100 moa sounds like a mortar sight to me.:p You could get the same effect if you shot a 22LR @ 500 yds. But seriously, a long action scope rail with 100 moa will be about .200" taller in the rear.

[upSLIDEdown]

Oh I realize that. I'm not looking to go that big, but something bigger than a 20. The 40MOA from Ken Farrell might be what I go with. Just wanted to see what other options were out there.

[bootsmcguire]

Go with the Sig Zee rings. You can go +20MOA in the rear ring and -20MOA in the front ring to get 40MOA total elevation, plus if you mount on a 20 or 40 MOA base then you can get to 80MOA.

The Sig Zee Rings are the most versatile way to go IMHO.

[upSLIDEdown]

I've just always been skeptical of something with that design. Similar to camber correction bolts for a lowered car. I've had them before and they slipped after a big jarring bump. I can't help but think the recoil of the rifle would do the same thing. Maybe I'm wrong though. They would certainly be a good starting point though if they work and hold true.

[bootsmcguire]

Mine always have held nice. I know what you mean, but you have to think of it more like a collet type holder rather than an adaptation. Collet type chucks and holders hold things very tight and true, and these are basically the same principle.

The beauty of it is you can use both front and rear for elevation corrections or use the rear for elevation and the front for windage by using the offset inserts sideways in the event of a misaligned receiver or untrue bases or something. I was skeptical at first myself, but after buying a set and giving them a good shake down, I am sold on the system and have used them for almost all my scope mounting tasks since.

2 sided tape on the inside of the rings should hold them, I'd think. Might take some doin' to get the reticle straight.

But why would they slip? They aren't shims, really. They fit the inside of the rings and squeeze the tube.

Maybe that's what boots is sayin?

Yup pretty much.

[upSLIDEdown]

Think they'll stay put on a 338 Edge?

[yorketransport]

I use a set on my 375 BME, so I can promise you that they'll hold up to an edge. The signature zee rings work beautifully when mounted on a steel rail. Don't wast your time with the windage style bases though when you get in to he bigger calibers. I've sheared off a few of the windage (not the dovetail) bases in as few as 10 shots on the bigger guns.

If the Sig Zee's hold up on the 375 BME, then they will survive most anything.

[geargrinder]

They hold on my sporter 338RUM holding my Nightforce.

Kirby was a big fan of the Signature rings for his big boomers. Now he uses multiple sets of Nightforce rings.

I heard a while back that EGW could modify one of their bases to whatever cant you wanted. I never looked into it myself, as I have no need for it. It may be worth a call to them to find out if you were interested. I've found their customer service to be pretty good.

I can barely survive my BME!

[bootsmcguire]

I can barely survive my BME!

After seeing that round first hand I am not surprised. It sure looks like a real handful.

It does make a great testimonial for the Sig Zee's holding up to it.

[upSLIDEdown]

Say what? Sorry, not super familiar with that terminology. I have an EGW picatinny base on my current gun. Got pics showing the differences of what you're referring to by chance?

[bootsmcguire]

We were referring to the 375BME (http://www.savageshooters.com/showthread.php?16365-375-RUM-Improved-(Box-Monkey-Express)&highlight=375+Box+Monkey+Express) wildcat cartridge. Its a wildcat round that yorketransport designed. It shoots 350gr .375" bullets with about 110grs of powder at over 3000fps IIRC. It really generates recoil and thus shows how well the Burris Signature Zee rings are capable of holding your scope.

If you are referring to the Sig Zee rings themselves this VIDEO (https://www.youtube.com/watch?v=wcRAX5OLtJE) should help.

[upSLIDEdown]

Sorry boots, definitely meant to quote this about the different bases.
