I have been very busy lately, traveling all over the U.S. for work. I have just recently had a chance to shoot some loads made from some other's resized brass. I only had time to load 10 rounds, of which, all fired. Only one of them did not fire on the first pull. It had to be pulled out and then it fired just fine. I will load more, when my schedule permits, and post another follow-up. Many thanks to those who sent me brass, I really think I have found my problem.
Thanks, Dinny
