New Guy here,
Just started loading for Steel Challenge and after a couple thousand rounds I have settled on 125g Blue Bullets TC (9mm) over 3.8g Sport Pistol. This load has been reliable and a joy to shoot in all my pistols. I think maybe this is not news to a lot of you guys.
What did surprise me, was switching from CCI to WSP primers. Here are my chrono data for the above load with different primers. 2 guns (G17 and CZ P-01), 10 shots each run, listed in order of data collection:
WSP, G17, 1037 fps, 23 ES, 7.4 SD
WSP, CZP01, 1002 fps, 20 ES, 6.8 SD
CCI, G17, 1043 fps, 45 ES, 16.2 SD
CCI, CZP01, 1004 fps, 60 ES, 15.7 SD
WSP, CZP01, 992 fps, 25 ES, 9.6 SD
WSP, G17, 1037 fps, 31 ES, 9.2 SD
CCI, G17, 1045 fps, 43 ES, 13.0 SD
CCI, G17, 1065 fps, 65 ES, 17.3 AS
I know it's a little overkill, but I was quite surprised to see the improved SD with the WSP primers. I've always liked the CCI primers cuz they're easier to get in the pickup tubes, but I think I've convinced myself to switch over to WSP primers. Is this unusual, or have I just rediscovered the wheel?
