...after 1 loading? I'm going through the Remington brass I used to make some test loads for my Bergara B14 7mm-08 and out of 50 rounds, I found 4 cases with split necks. I haven't had a split neck yet with any loads I've done ranging from .308 to previous 7mm-08 loads for a different rifle to 6.8 SPC.
This brass was saved from commercially loaded ammo and has only been fired once. It is not range pickup or bought from another source. I cleaned this brass by wet tumbling with water, stainless steel pins, Dawn dishwashing detergent and a little bit of lemishine for no more than 4 hours (probably a bit less). The max load for testing I used was Hornady 139 grain BTSP bullet, Remington brass, Federal 210M primer and 43 grains of Varget powder loaded to .05" off of the lands and grooves. I trimmed the brass to 2.030" which is right in the middle of what my Hornady manual recommends. My test loads ranged from 41.0-43.0 grains of Varget.
So my questions are these:
Am I unknowingly loading hot? Or...
Is Remington brass really this weak? Or...
Is there a potential flaw in my chamber? Or...
