I started out with 125NBTs out of that rifle. They worked great for moderate range deer shooting. I only downsized to further reduce recoil. I'll see if I can find any old data. From memory, I was running them slower, 2500ish, with the same hodgdon powders. I don't think I owned AR-comp at that time.
None the less, given your extra 6 or 8" of barrel length, you should be able to scoot them along. You won't have any issue with 200yards.
