It is a fun cartridge. One MOA is no problem. I found the throat on mine is quite long, and 150 NBT were the lightest bullet that would allow the bullet close to the rifling, and still have a little purchase in the case neck.

Did you experiment with jumping them a bit? I have several 308's that shoot well under MOA for five shot groups with the bullets jumping 1/8" or so.
No, I only tried working up the Big Game load with 150's, then dropped the deer shown in 2012. It's missing a scope at the moment, but at some point I'll get back on it.
