Soot on standing breach
While experimenting with Green Dot in my 10 ga. hammer parker,with a step at the forcing cone, I found that I was getting some soot on the standing breach. The pressure and payload are about the same as when I use my regular load of Red Dot. I was thinking of upping the amount of Green Dot a few grains to about 7500 psi in the hope that a little more pressure might seal the case against the chamber a little tighter.
The fired primers do not appear to be the cause of gas leakage as they are a tight fit when reloading the cases.
Has anyone had a similar problem with low pressure loads?
