Dennis, Thanks for the page. I forgot what a great resource that book is.
Dalej, Thanks for the advice. I've worked this load up to 46.8gr w/o any problem. I did happen to have brass from unfired through 4x fired (all un-annealed) and I measured the extraction groove. on unfired brass, the groove is .4065"-.407". On 4x fired brass, it is .4075". I do occasionally get primer pockets that are easier to prime than others but nothing dramatic.
Bayou Shooter, I trim brass as part of the reloading process after resizing, every time. Unfired brass was trimmed at 2.005". 4x fired brass was trimmed to 2.011". Chamber length is 2.035"
Webster, I realize that my charge is higher than book recommendations but I worked it up carefully to 46.8 w/o pressure signs. Also, see my reply to Dalej re extractor groove dimensions.
I have fired hundreds of rounds of this and higher loads with 3x-4x fired brass without any problem. I really think that the problem is related to the annealing. One other consideration, prior to annealing, I used SS tumbling for the first time. Case mouths were slightly "belled" (more of a burr really). I resized and demurred them. not sure if that is a possible issue.
Also, check out the attached photo of the annealed brass. Does this indicate over annealing?
Thanks for all of the replies.
