Shooting pretty good for me. Under 2" at 25 yards. Nice mild, easy to shoot load.
The question I have is about the gas checks. This is my first GC mould. I dug one of the bullets out of my backstop and it looks like there is lead being blown back over the check. There was some slight leading visable just forward of the forcing cone after 30 rounds or so. Accuracy didn't seem to fall off at all.
Here the bullet. Is the lead on the check normal? Seems like it's not "checking gas" too well if lead is getting on it.
