[QUOTE="specweldtom, post: 1328064, member: 2580"] I have used throating reamers so that longer, heavier bullets or blunter ogive bullets, in hot loads, could be seated well off the rifling, usually long range rifles with Sierra mkhp bullets. After I got a Hawkeye borescope, I stopped using separate throating reamers. Every throat done with a throating reamer showed circular tool marks (weasel words for rings). The rifles shot great so I never knew it until I started 'scoping them. OK, so if the rifles shoot, what's the problem? Simple, now I know the rings are there, and can't make myself do it anymore. I agree with Nesika Chad and JE Custom. Just order a reamer with the desired throat ground into it. I do not know why the throating reamers made rings, but I talked with two top reamer grinders and they made several recommendations to try to stop them. None worked. I have since theorized that the throating reamer, even though piloted, doesn't have the stiffness, torsional rigidity, or stability of a chambering reamer. May not clear chips away as well either....Just my best guess. Goof hunting, Tom [/QUOTE]
