[QUOTE="Pdvdh, post: 1462779, member: 4191"] One additional update. The burn rate of the powder used to fire form the parent cases seems to play a role in the resulting case shrinkage. I use SR7625. Elkaholic was using a faster burn rate powder and having a less successful result. We discussed it and suspected the powder burn rate could be a factor. So he then switched to a fire forming powder with a burn rate similar to SR7625, and then had good results. I think the faster burn rate powders don't hold their peak pressure long enough to cause permanent case expansion. I continue to have positive results using SR7625 as my case fire forming powder. You could PM '[B]elkaholic[/B]' and ask him which powder he ended up using. I don't remember which one he used. [/QUOTE]
