[QUOTE="woods, post: 811697, member: 6042"] Certainly the neck brass will springback some after firing. Not sure if the heat from the firing will have any annealing effect. 3 of the loads in the original post are custom tight necked chambers, the 6.5 rem mag, 338RUM & the 280AI. The 280AI is stamped ".313" neck" but the fired case OD is ~.311", so there is ~.002" springback on the neck after firing also. The 375 Ruger was chambered with a standard reamer, at least that is what I told the smith, and the fired OD is .005" larger than the loaded round OD. Figuring a little springback, I would assume I have .007" neck clearance. The 06 is a factory Steyr and it has a .0085" difference in OD between fired neck and loaded round, so it must be close to .010"+ neck clearance. [/QUOTE]
