I wonder what the cup pressure was on that load? Years ago there was a bad batch of RL22, and was a recall. I was told from a tech at Allaint that loads that ran 52000 to 54000 cup's with RL22 and with this powder would go as high as 85000 cup with the same loads, I had 15 pounds of it, they told me not to use it and sent me 20 pounds and told me to spread the rest of the bad lot on my yard. I took it and put it in a 5 gallon metal bucket and put the fuse to it. Awsome light show, never lite that much powder off at one time.
