[QUOTE="QuietTexan, post: 2297541, member: 116181"] Essentially what we're all saying is before the first shot you have to decide on several things to build the initial round: bullet, powder, charge, primer, COAL. Which of those is the first variable you mess with after you make your initial choices is the question - we're discussing which of the initial assumptions is the best to change first. I said coarse seating depth first. Doesn't mean that changing powder first is wrong by any means, a simple explanation of why two rational people make the opposite decision in this case is the "change charge first" guy feels better about his seating depth than I do about my powder selection/charge. There's approximately all the data in the world about H4831 in the 6.5-284 case with 140s, should be a rock solid starting place on the charge weight in that situation, but VLDs can still be tough to tune - seating depth first. Why might he feel better about his seating depth? I feel better about depth in some cases also. I'm getting a reamer made for a new barrel, the first adjustment I will make in that loading cycle will be charge weight because the chamber is going to be cut a certain way for the bullet that will be sat in it. I'm going to start a lot closer to the optimal seating depth in the first place compared to stuffing a 115gn Berger into a factory 243 WIN chamber, it should shoot well out of the box at 0.020" off because it was built around that assumption. Still going to test it, but should be easier than going into a new chamber I know nothing about. [/QUOTE]
