View Full Version : Contouring a barrel

July 23, 2007, 07:06
I had a DPMS .308 barrel contoured / lightened / turned down for my .308 AR project.

This Sat I sighted her in. 5" at 100 yards. 10" at 200 yards. Consistent groups, but....

Needless to say, that ain't gonna get it done.

Do you think its possible the contouring knocked the barrel harmonics out of whack?
