Bighorn, I see you have posted on two different threads extraction issues with your HS6 load and WW primers (WLP?) I loaded that same charge, Starlins brass, 410 CP WFNGC, but using Federal 150 primers for my Ruger SBH Bisley 6 1/2 inch without any extraction issues at all. Accuracy in my gun wasn't terrible either. Go figure.
