[QUOTE=".7mm., post: 2949806, member: 127719"] Trying to determine which sizing die or neck bushing size to buy for my 25 cm. Using alpha brass and a 21st century. 255 expander mandrel (actually its the black nitride turning arbor which is 2 thou under bullet diameter) Right now with the Virgin alpha brass the mandrel just plops right into the case, while the .256 expander i also have will actually expand the neck but im not sure if I want to run 0.001 (or 0.0015 with spring back) yet. Maybe I will later once the rifle tells me what it likes. But right now should I just go with the Virgin alpha brass neck tension the way it is? Seems like they are all pretty uniform but I don't have pin gauges and can't really trust my mitotoyo to that degree. Also looking at the f class products 25 creedmoor sizing die in the 282 neck od for my sizer...is that going to be sufficient in giving me enough initial neck tension so I can then expand using the 2 thou mandrel? Or do I need to look at the SAC bushing die [/QUOTE]
