Thank you !!! Answers my question to a T .

BTW....... did you ever experience any temperature sensitivity with the R-22 ?? I developed and loaded a batch of 120 SMK's in the fall a couple years back. They shot very well. The following summer they were COMPLETELY off the wall..... blowing primers, nearly locking the bolt up.....
