Once again, thanks for the quick responses to my powder questions/problem.
Over the weekend, I sat down in front of my Rock Chucker and did 25 rounds with the Clays that I had in stock. Yesterday I went to the range and put 10 through the P239 and 15 through the P226, flawless operation and the clean that I love in my 12 ga Red Label!
Now that I know the round works for me, I'll set up my Dillon Square Deal and have at it.
Problem solved, that's why I love this forum; you always get an answer, even if it is just a smart a** reply, but generally the right answer is there.
