Canted scope base questoon

[Roll-Yur-Own]

Hi guys, I'm looking at getting a one piece scope base for my cheytac. I have a 20 MOA rail on there now. Was looking to see the advantages or disadvantages of getting a 20 MOA or 40 MOA scope mount.

That would depend on your scope and where you want to zero. If the scope has enough elevation then 60 moa of cant would be fine and allow you to reach out farther.

If you want to zero at 100 you can run up to 1/2 the amount of travel available in your scope. eg: If you have 120 moa in the scope you can run 60 minutes of base. This will allow you to use all the internal travel of the scope.

Alternatively if you want it's possible to exceed this number and run a zero offset. Tons of guys that shoot ELR will run a base that does not allow them to come to a true zero at 100, they then enter into their solver how many inches high at 100 to allow them to extend farther out.

If I was going to run a zero offset I would decide what's the closest target I intend to shoot with that rifle. Say 1000 yards, figure out my dope for that. Call it 20 MOA, and my scope can handle a 60 MOA base so that puts me to a 80 MOA base and will give me crosshairs on target at 1000 Yards and I can dial up from there.

So if I have a 20 MOA base and my scope has 100 MOA I sight in 30 up from the bottom and it gives me 70 to dial in?

What's the real deal about optical clarity if you're not in the center? Because if this is true, I could put another 30 on there and use all 100

Sounds like you understand.

I run a couple scopes right on the bottom and I can't tell the difference optically, but my eye's aren't very good and I'm no glass snob. You can remove your zero stop and crank it all the way down and see if bothers you.

That being said even if you max it out how often are you shooting at 100 that you really care? the optic more likely ends up dialed into the middle of it's elevation anyways, targets from 1500-2000

I think you need more than that if you want to stretch that beast's reach.

Most modern scopes will be fine at top or bottom of travel and clarity. What scope are you using exactly?

And if this will be a rifle used at 1000+ all the time then a 100 yard zero is not really needed and you can zero at 1000 and have a bunch of elevation to dial from there. Just need to do a little math about your 1000 yard data and scope available elevation and then how much cant you can put in the base/mount.

 

[Roll-Yur-Own]

Yes, I went with the 40 MOA Hawkins 1 piece. I really don't need 100 yards 0 other than when I'm first getting started and even then I think all the way at the bottom I'll be at least 200 or 300 yard 0. With the 20 MOA this will give me a ton of up elevation. Ultimately, I plan to have it zeroed at 1000. Using ATACR 7-35x56

I got the same Hawkins mount with zero cant for my 6.5x284 which I'm not really going much over 1200 with anyway.

 

[Taylorbok]

You likely have hold under in your optic also.
You are only gonna have a 10 MOA offset so you should be able to hold under if you choose to shoot at 100.

 

[Roll-Yur-Own]

This is my ELR rig so I doubt I'll be anywhere near 100. I really appreciate all you guys given some good advice. This is my favorite forum. That's why I've been here a long time.

Dont buy another rail. Get you some Burris XTR Signature rings. You can add uo to 40moa of cant in the rings.

 

[Roll-Yur-Own]

I didn't get another rail. I have 20 MOA rails on both guns already. I went with the one piece Hawkins mount. 40 MOA for the CT and zero for the 6.5 X284.

I run those rings on a 22LR, not sure I'd trust them on something with actual recoil.

Never had a scope move up to 338 Lapua.
