How many MOA do I need to reach out to 1000 yards?

Not in this calibre. Grendel is slower than a wet week thanks to its small case and so is not suited for long range shooting. Your bullet will get there but will be wobbling around the sky after 800yds as it crosses into transonic (1,350fps). As it slows the bullet's centre of gravity moves forward and in a pointy supersonic shaped bullet that means it starts to go unstable. Groups blow out, and by 1K it is subsonic.

With 20MOA cant you have enough to make 1K easily but with 30MOA it is useless elevation because the calibre is going to let you down if you want to use the extra elevation 15.5 (scope) + 9 (base) = 24.5Mil max elevation = roughly 1,400yds/900fps. Trying to be accurate at that range will be like driving jelly.

This is a great reply.

I tried running mine at 1000. It didn't work because E-targets needed it to be good supersonic still to work.

I tried it at 1000 on a gong range. It did work pretty decent, but I definately needed a friend on strong glass to see and call the impacts. It's quite mild at that distance, so not a lot of noise or plate movement on impact.

Grendel is a damned fine round, and can make it to 1000 yards, but where it shines and dominates is more on an NRA or CMP 600 yard midrange match. (IMHO)
