[QUOTE="Jim1 AB, post: 197752, member: 7531"] I'm building a 6.5 Ruger and plan on using 7mm Dakota brass. I expect I'll have to ream or turn the necks, even more if I have to use 375 Ruger brass. From what I'm reading on a thread search for neck turning .011 for neck thickness is a good average. Reamer drawing shows the neck cut at .298 so with a bullet diameter of .264 plus a neck wall thickness of .011 a loaded case should be .275 with a .023 difference. Is there a rule of thumb on minimum for the case to expand on firing. A little help in the procedure and equipment needed would be a great help. Thanks in advance for the help Jim [/QUOTE]
