Rifle Scopes MRAD scope and MOA base

[pby5cat]

A friend is getting a Savage 10FCP-K in .308 and the scope is a SWFA 3-15 MRAD. If the base is 20MOA than what does that do to the Millradian math?

 

[varmint slayer]

Nothing. Just zero the scope and move on.

 

[Aloysius]

What he said ^^^^^ absolutely nothing.


The 20 MOA base just adds extra elevation as you can only adjust up and down so much depending on the scope.

 

[JesseSB]

It gives a Mil scope about 5.5 additional Mils of elevation adjustment is all. Better for LR shooting. Ever had a scope run out of elevation adjustment? Once zeroed, the 20 MOA, roughly 5.5 mils, are never in the correction equation, it simply leaves more internal adjustment available in the scope.

 

[Notso]

Yeah, I think the 20 MOA term is a holdover from the US who has traditionally used to doing everything in MOA. As has already been said, its just a base with extra elevation built in so you don't max your scope out on elevation at longer ranges. Once the scope is mounted and you have your zero set, the base has no part in the ballistic calculation process. Ignore that its there.

20 MOA = He has a rail with 5.56 mils cant.
That is how much the scope borrows from the cant in the rail. It has nothing to do with the math only you now have a much larger range to adjust for drop/elevation.

Someone could make a killing putting out a 5 or 6 mil mount.

^^^This, we could call it the 5.56 mount

Too bad it's actually 5.816 mil...

Well, the 44 Magnum is actually a 43 cal so u can fudge a little.

 

[Lowlight]

Spuhr Mounts have it written in both Mils & MOA on the side of the mount.

Without doubt, you would generate internet sales.

To be honest, after zering my scope, i have never turned the elevation turret. I just hold a negative value in my scope and shoot. 1000 yards is -6.5mills on my 6.5 creedmoor.

Thank you for the insight.

I hate MOA and the imperial system! LOL!!

TO make sure, it would have to Countersniper brand.

So you're holding below the target??? What, did you zero it at 1500 yds?
