I would recommend that you up your dwell then, it seems you are shooting fragile paint. What brand did you use?
I run 1 turn in from flush and a stock dwell of 10.5 to break in the marker.
I've spoken to several PE reps and they confirmed there is a break-in period for the marker. I would keep it at 10.5, run about 20 cases through it and then head off to the chrono to follow the dwell setting guide.
I usually try to keep my dwell a tad higher so I can shoot brittle to hard paint year round without having to touch the dwell everytime the temp changes.
If you can bring a laptop to the chrono, follow this guide:
