Just keep shooting it until the groups stop opening up.

After reading that I have a warm fuzzy feeling about my BCM 16" middy. :D

Yeh, I feel pretty good about my Noveske with M249 machine gun barrel and extra thick chrome lining, and a little less good about my Stag 2T with barrel made out of 4140 steel.

The original barrel on my Colt HBAR went at least 7,500rds before it would no longer group well enough to be competitive in Highpower. By that point, headspace with the original bolt was kinda rough too, only gauge it would not lock on was a 5.56 Field gauge.
