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?
