Rifle Scopes Adding 20 MOA canted rings to 30 MOA base - Is it really 50?

[RPRRob]

Just curious if anyone knows the trick here...

If you add 20 MOA of cant in the rings to an already 30 MOA base...does that TRUELY give you 50 MOA? It seems like stacking two sloped items would throw that calculation off a bit. Can't be that easy, right?

In my mind, if i put a 20 MOA canted device on flat surface......it's pointing down 20 MOA. But if I put that same 20 MOA on something that's already sloped.....

Get what I'm getting at?

I'm trying to figure out how to get the most out of the 125 internal elevation in the scope without maxing out the bottom, and also what ring height, etc.

I need to mount the Razor HD 5-20x50 to my new Ruger RPR in .338

Thanks in advance!

yes the moa will stack.

so you would be at 50. sometimes when people do this, depending on your set up, you will run out of downward elevation and not be able to zero at 100.

 

[RPRRob]

Thanks! Overthinking it. That's easy.

if you have 30 moa in your base. i would just stick with that and get 0moa rings/mount. that's usually plenty of cant unless you are shooting ELR or shooting .22lr long distance

Pushing it out to 1.5 miles. Dope says I'm going to be in the 140ish range in MOA out that far. With 125 internal...(vortex is usually pretty dead centered) and putting 50 on it...I should get somewhere around 112.5 up. Add another 35 in the reticle...that will get me close.

If they aren't on a trajectory for orbit by then........well I'll just shoot .22LR like you suggested then. Haha.

 

[Olen_4504]

haha there you go. sounds like you got it all figured out.

good luck! you should report back how it goes

 

[RPRRob]

Reporting back will probably DEPEND on HOW it goes haha!

Unless you mount the rings backwards. Then you have 10 moa...

EGW will make custom rails to 60 moa, I believe. Give them a call. I have talked with them a couple times and custo.er service is as food as it gets.
