[QUOTE="MontanaRifleman, post: 748534, member: 11717"] Never heard the "Gelding" descript before. I'll have to remember it. This is interesting since I was just visiting my smith about a week and half ago to determine the reamer specs for my New 300 RUM (currently shooting a factory Sendero) We are goibng with the PTG 300 RUM Match which has a little tighter neck. We also discussed neck sizing vs FL, neck turning, etc. Going into this project a while back, I was going to turn the necks but after talking with him and others, I decided not to. He is an avid shooter and long ranger as well. He is a FL sizer and is happy and successful with it. He also said, that when a round is chambered, it will sag under it's own weight and not not be perfectly centered. If it does, I suppose it might throw the neck off center a little when the round is discharged? I don't know. My necks seem to come out of the chamber fairly concentric. Anyway, I would say that if there is a lot of variation in neck wall thickness, it would probably be a good idea to turn them, but I haven't seen a lot of variation. I also like the idea of bringing the expander back up through it to get any variations pushed to the outside. I don't think that would throw the necks off much, if at all, if your only pushing it out 1-2 thou and the inside of the neck is lubed. That could be easily measured and i will be doing just that when this project is complete. [/QUOTE]
