I shortened the COAL by ~ 0.015" to 1.115", shot two mags with no DPP impacts Maybe that was the fix, or I needed to run another mag.
I also ran 2 mags with 5.2g of CFE, still no DPP impacts, avg bullet speed 1140 fps. The CCI primers are flattening out at 5,2g.
Per suggestion I then replaced the extractor spring as well. Extractor claw clearance is 0.050" to 0.069", mine's measuring 0.060" GTG.
I'll report back after a few hundred rounds have been through it.
