Hi all. I get what looks like a tiny bit of partially burnt powder ejected from my Glock 17 with the loads listed below. No other issues with the loads, except that the 3.7gr is a little weak locking the slide back on the last round. My groupings are tight and the gun cycles fine. I only noticed it because I was shooting bench wrest through the chrony, and I got a few little flecks of black on my notes sitting to the right of the gun. Doesn't happen all the time, though.
124gr CMJ
Titegroup
COL 1.135
Mixed head stamp, once fired
Load 1: 3.7gr ~1030 fps
Load 2: 3.8gr ~1040 fps
Load 3: 3.9gr ~1050 fps
The COL numbers online are all over the map for 9mm. Titegroup says 1.150 max. My remington factory rounds are 1.113, noticeably shorter. I'm pretty sure my crimp is tight enough, so I was going to shorten the COL to increase the burn time. I tried firing up close on paper, and I didn't see any telltale circular burn marks.
Thoughts? Anyone else noticed this?
