[QUOTE="LouBoyd, post: 270058, member: 9253"] The "ATF" method is to place a rod down he barrel until it rests on the breech or bolt face with the action closed, with the firing pin retracted. Then mark the rod at the muzzle not counting a >removable< brake or other muzzle device. Extract the rod and measure to the mark. I'm not sure if that measurement method applies to revolver action rifles, but it does to other actions. For a quick measurement on a Rem 700 just measure from the 1/8" diameter gas relief port in front of the ejection port to the muzzle. That will be close. [/QUOTE]
