[QUOTE="Idaho Lefty, post: 3096985, member: 104437"] YES, they are Cold Hammer Forged Barrels ( the precision Hole and the Rifling Part ). BUT, the Chamber is "Reamed out" afterward and has, minor "Burrs" / Sharp Edges at, the "Throat area" where it meets the bore, left. ( AFTER Reaming for, whatever Cartridge, they want to make ). ALL Barrels are Bored, Rifled, then, the Chambers are cut, LAST. My Break-in Method, is some Very MINOR "Polishing" at, the edges ( and Ramp ) of, the Throat area and the sharp Rifling, "lands". Those sharp Land edges and throat, being, a bit "Polished" means that, LESS Copper and Carbon can, "latch on to it during firing. JB's is, a Mild abrasive, just don't go Crazy and,. overdo it.
