Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
What brand barrel?
I have several Noveske barrels and they are at .104"

Noveske barrels are a little looser, and typically need more powder for the same velocity, so that would be consistent.
Good Shooting, MarkCO www.CarbonArms.us www.crci.org
