Mark, thank you! This is great. I loaded up 6.6 gr of HS-6 in my Glock 19 with an RMR 124 gr MPR seated to 1.092". This is using a CCI 500 and Perfecta brass. My average velocity was 1181.6 fps. I felt this was getting too hot so I didn't shoot any larger loads. However, the accuracy at 6.6 gr was excellent.
