I've had several barrels from Odin Works, Faxon, & Black Hole Weaponry in various calibers. All could shoot 1/4"-1/2" groups with handloads.
So, Who supplied their barrel blanks?
Odin gets their from Mcgowen.
BHW is now Columbia River Arms, and they make their own.
According to Faxon they make the entire barrel including the blank and only send them out for nitriding.
