[QUOTE="Bart B, post: 666076, member: 5302"] Several barrel makers I've asked about fluting all gave the same answers. Fluting a finished barrel: * if a button rifled one, it'll probably end up with larger bore and groove diameters under the flutes. * hammer forged ones will probably end up with smaller bore and groove diameters under the flutes. * those cut rifled ones typically change bore and groove diameters the least. The all said any rifling method can be great in a fluted barrel, but only if the barrel's fluted before the gun drilled blank is reamed, rifled and lapped to tolerances. All three also said there's no accuracy difference between fluted or solid ones with equal quality bore and groove dimensions; each one whips and vibrates at its own resonant frequency for each shot fired regardless of the cartridge or load used.
