I?m shooting 14.5 gr of HS6 in my SRH. Initially I was having leading issues. I bought me a set of pin gauges and learned I had thread choke (.002) just passed the forcing cone. After fire lapping to remove the constriction, I no longer have leading issues. It does have extraction issues, but it?s not because of pressure issues - it due to chatter marks in the chambers.

It takes 43 muscles to frown and 17 to smile, but only 3 for proper trigger squeeze.
