Megahurtz,
Yes, you need a 20MOA rail to shoot 1,000 if you want your target towards the middle of your scope's field-of-view. The closer you are to the centre of the field of view will have the least distortion. Otherwise you will need to use hold-overs, which will work, but not as precisely as having a nice crosshair to assist.
Sounds like your whole settup is a handicap for what you are trying to achieve. An (unreasonably) long 28" barrel fixed to a light-weight/flimsy AR15 receiver, using the smallest popular 6.5 calibre, with a scope that only has 20MOA of usable travel.
What model is your Sig scope?
On a side note, where did you get the data for Hornady American Gunner in Grendel? I visited their website and AG is not listed. They advertise 'Custom', 'Black' and 'Frontier' in Grendel only. Is this a limited run or a discontinued line? (also, hardly anything mentioned in previous threads for Grendel AG).
