All the brass is Rem 221 Fireball expanded out with Redding dies, all flash holes trued and all trimmed to 1.355, 3 shot groups.
I have loaded 16 grains of H110 for the AR with a M1S barrel for super sonic but I have only
fired a few into a back stop to make sure the action would function. I have 200 rounds loaded but have not gone out yet to break in the new lower.(crummy weather)
I have a 16 inch barrel with the carbine gas tube. I am going to try some 1680 for subs in it.

Thanks for the info
I don't think 3 shot groups really tell the whole story of a particular load or bullet.
I can shoot an ocassional sub 1" 3 shot group with the 175 milsurp bullets either in my 308s or 300 Whisper but I rarely shoot a sub 1" group with 5 or more shots in a group which I think is a better indicator of a good load.
