[QUOTE="Hired Gun, post: 961818, member: 1290"] To start with JGS has a staggered flute arraignment to prevent chatter. PTG are evenly spaced. JGS are finished to a much higher tolerance as shown in the pictures. PTG then the JGS. These are taken of the throating part of the reamer but the finish follows the full length of the reamer. Under magnification these ridges show up right in the throats where there isn't much you can do about it other than shoot it to break it in. In the body a little 320 or 400 will clean them up where the JGS doesn't need anything.
