What barrel and buffer will you have?
Yeah I know, but I just set them a bit long knowing I will have to re-seat them. If I get the barrel and find that they are close to 2.250" at the lands, then I will set them to that. I just didn't want to set them too deep and then regret it.
It will be a 24" lite barrel from AA, with a standard rifle buffer (I assume) from Palmetto state armory (their A2 stock kit) No adjustable gas block of anything. I'm hoping that the gas will be about right.

XBR does very well, but the cliffs edge is sharp, a little too much turns into a lot too much REALLY fast!
Great powder and very stable temp wise, though.
Yeah, thats about what I've found out. Really I probably would have only gone to 28 gr if it wasn't for this thread.
