Yep and I have a few loads using SPM primers with HS-6 which do seem to be better but really nothing special . I have even used small "rifle" primers in some 357mag loads using HS-6 . That said I started loading 12ga last year ( yeah perfect time to start loading something new haha ) I had several pounds of HS-6 collecting dust and it turns out it's a powder I can use in 12ga loads so that's what I'm doing now . Also have a couple 44mag loads using HS-6 which seem to do well .
HS-6 is one of those hard to ignite ball powders that require a magnum primer to burn clean.
