Your base needs will depend on your scope elevation travel. Most of the high-end scopes don't really need a 20 MOA base for within 1000yds. You should be able to push the 130gr VLD up to about 2680fps with a 28" barrel and the right powder.
BjornF16 is getting 2585fps with the 129gr Interbond from his 20" Savage using CFE223. In the bolt action, you are able to take advantage of the Grendel case's 60,000 psi pressure capability, but slower-burning powders can help keep peak pressure down.
At 800yds with the 123gr A-MAX going 2750fps, you will only have 6.7 mils of elevation at sea level, 59 F. What State do you live in? This rifle will be capable of reaching well past 1000yds, so you might consider an MOA cant base for when you find an opportunity to shoot at farther ranges.
I would get a good sizing die, maybe with bushings so you can keep control of how the brass gets worked, and get a Forster or other micrometer seating die. You will be able to play with seating depth much more since you have a bolt gun.
Well I just ordered the barrel, it should be a monster for sure.
It is a Douglas 7-W contour so it is about .930 at the muzzle, barrel weighs about 6 lbs.
We will see how this project goes as time goes on.
Thank you guys for the mount info, it is very helpful, I plan on feeding her a diet of 123gr AMax's ;- )
PS: I live in the high desert of California.
