Rifle Scopes Nightforce NXS 12-42X and 20 MOA base - 1,000 yard problem

[Tempest 455]

We shot 1,000 yard F class last year with different rifle/scope. So I bought a new combo for this year. I thought for sure I would have enough internal elevation with a 20 MOA base on my F/TR for 1,000. Does not look like it. Bought a Savage F/TR rifle used and it had a 20 MOA base on it. Guy had shot it at 1,000 yard F class matches.

I installed a Nightforce NXS 12-42 which has 45 MOA internal. I took it out and got 100 yard zero and then 500. Needed 11 MOA up from 100, which jived w/ my chrono.
Went to add 24 more MOA up and she stopped after another 12 or so.

Took it all the way back down and found something strange. At 100 yard zero, it has 19 min down until it stops and has 24 up until stops. I would think with a 20 MOA base, it would be less than 19 down? Velocity is 2,750.

Looks like I need at least a 30 MOA base, if not more. He must have had a scope w/ more internal than me.

Anyone else run into this w/ the NXS for 1,000 yards?

#1) Are you sure it's a 20 MOA base?

#2) I've never heard of a decent scope with that small (45MOA) of elevation adjustment .

Was told it was and sure looks it.

The 42X NXS, yes has that little.

You are right. I went back and looked at it and although it appears to be canted, because the way it's made, it's an illusion. I measured and it the same front and back.

Guy told me it was 20. Maybe it's a blessing in disguise because 20 wont be enough anyway. So next question, should I go 30 or 40? This will strictly be a 600-1,000 yard F class gun.

You might have to, especially for that distance specific gun. The 42x has the least amount of travel of all the Nxs scopes. I have a 40 moa base on my .338, but with a 5.5-22x (100moa of travel) and get a 100 yard zero... However, I don't shoot F class, so 22x is just fine for me

Yup, got a 25moa base from Murphy Precision for my Rem 700, I didn't want to cut it close with a 20moa base.
