FireDragon is making pistol barrels by using EDM (Electrostatic Discharge Machines). They claim 50 millionths of an inch accuracy and a surface smoothness of
16 RMS or better. That seems very straight and very slick and ought to be a jim dandy barrel.
I'm thinking of getting one in 357 Sig for my Sig P229. Does anyone have any experience shooting cast bullets in these barrels?
