This is the only reamer I have used. I used the "shop manual" to set up and followed the instructions to get a "match grade" fit of barrel to bushing in less than an hour working slowly. I purchased the bushing mandrel at the same time to fit the bushing to the frame, also in less than an hour. I'm looking forward to seeing increased accuracy.
Both products worked as advertised and I would recommend both.
