At 24.5gr it's a hair lower than the AA at 24gr. So it's a compress ever so lightly. But after testing I think I'm gonna use 24.1gr and hope for 2800 flat.

I've got a rather silly question: Why would you want to load to max velocity? I would think that the 'name of the game' is to find out what load is the most accurate (bullet, powder, case, primer) for the weapon you are shooting. Some weapons prefer heavier bullets, some need the lighter ones because of rifling twist, others don't like certain powder/primer combos.

I've been reloading for about 30 years now, and yeah, it's a pain in the backside to build small lots of ammo to test powder/primer/bullet combos. For example, my favorite load for my mini-14 doesn't work as well in a 5.56 AR platform gun, even with the same rifling twist. The mini will shoot 1" to 2" groups at 250 yards, the AR platform gun shoots 4-5" groups at that range with the same ammo. But for what I build ammo for, I'm good with that. I look for retained energy at the range I expect to use a weapon at and build ammo accordingly. Just my take on the subject.
