[QUOTE="VinceMule, post: 2854860, member: 122164"] Depends. If a guy taper bores or straight bores the chamber to within .015 or so from the final shoulder dia and within .050 of the finished chamber length, uses high-quality cutting lube, a finish reamer should last 150 chambers or more. On the other hand, if the guy just goes straight in with the reamer only, figure dimensions start to change from 6-9 chambers out, maybe. Of course, there is a big difference between reamer makers in heat treat, grind etc, and this is a huge can of worms. How many actually have the skill to pull an audit on a gunsmith's work? Finish reamers are only meant to cut .015 per side. [/QUOTE]
