Steve: I did test my loads with full mags. I loaded them up to with 10 rounds and sent rounds down range. I didn't load up with 10 +1 and I didn't test the load in all 8 of my magazines. Lesson learned. :-)
RustyFN: Thank you for your advice. These bullets are plated. Starting load for a 200gr lead or plated bullet is 4.2 according one source and 4.4 according to two others. 4.7 and 4.9 and 5.1 are the max loads for a 200 grain lead bullet according to my data. My purpose is to load light for GSSF comp.
I'm not opposed to increasing my powder charge if that's what I need to do. I would like to know why this load works for others and didn't for me. If I can fine tune it or switch bullet designs...that would be a plus.
Since I have 30 or 40 of these loads left, I'm thinking about pressing them down to 1.161 which is what Lyman's says for 200gr lead bullet. I don't really have them crimped. I just took the bell out.
