[QUOTE="shortgrass, post: 1761524, member: 24284"] It depends..... Large hunting cartridges are usually given more clearance than a BR chamber. I like to run about .003 on my own, personal varmint rifles. My 30/06 and .338 Win Mag (and my 300 Win Mag) have .004-005. The reamer makers give themselves .0005 tolerance for custom grinding. I think about all 'gunsmith' chambering reamers come with the neck portion straight, and not tapered. As I said, straight is a non-issue. [/QUOTE]
