[QUOTE="Trickymissfit, post: 900986, member: 25383"] I worked with a guy that brought in a Remington heavy barrel in the shop and fluted it with an old Barber Coleman hob!! He used a standard gear cutter, and the flutes were pretty, but the slight taper created a headache he never quit overcame. Took him about an hour after he got everything setup with a very light cutting load. Called me down to show it to me while it was still chucked up in the hob. Then he removed it, and found out that he'd made a serious mess of things! The barrel must have bent a quarter inch! I actually straitened it to within about .005". He then took a very fine pencil torch and got it within a thousandth. Barrel went from shooting half inch groups to two inch groups in a .308! And that was after a complete recrown and a heavy bead blasting. Four hundred dollars later he was back to shooting in the half inch range again, but he did own a good tomato stake. gary [/QUOTE]
