The Problem: My E-Mag's barrel measures .691", EXCEPT at the very tip where the chrome muzzle brake is swaged onto the barrel. There it measures .687". I would break paint just as it exited the barrel. Very odd.
NOTE: I measured the barrel (and all my barrels) with precision ground gauge pins, which come in sets in .001" increments. where I work we have them from .009" to 1.000"
The Solution: I carefully "Dremeled" and polished the tip of the barrel 'till a .691" gauge pin slid all the way through the barrel. It's shooting much better now, thank you.
