[QUOTE="TnTom, post: 361710, member: 21944"] bart I agree, the datuming you describe if I understand you are including the shoulder and a point on the body diameter would create a C/L line most accurately thru the case that would be the most accurate method to establish datum C/L. Milanuk, I would modify the set up and try to use a dia near the rim but not on it and possibly a ring on the shoulder. It would take some fabing to include the shoulder as part of the alignment as bart is referencing then it would be an excellent tool. If you you use two circle on the body to locate the case not including the rim it would still align accurately and you could indicate the shoulder. If the neck is turned it would be concentric. No reaming. I was referring to indicating the neck id before a bullet is seated when I said getting inside, not reaming. I was thinking you were using a something like the sinclair. I don't think the Hornady that uses a point on the ogive and the rim is a great setup. I've looked at so many in the last few days I need to go back and get them straight. The neco I think has too large of a bearing surface ( the 2 V's) though moving the case off the rim might be an improvement. [/QUOTE]
