[QUOTE="kgunz11, post: 2535917, member: 5110"] So that's not always the case. With any tubular bore style object, many machining processes can change the bore dimension. Some of that due to the process in which the material is made. In the application of a rifle barrel, some of us know how to machine the muzzle in a way that doesn't change the ID of the bore in a measurable manner. I can tell you that heavy passes and hogging the material WILL change the dimensions. Going slow and easy, with sharp carbide tooling, proper work holding, a good threading insert, and you won't get tight or loose spots. I have a 300WM #5 contour barrel in the lathe right now that I took a little video of that confirms this. I remember a time when people said fluting a barrel was detrimental to accuracy. There are very few absolutes in this world, and a lot of voodoo. [/QUOTE]
