Learned Sirs and Ma'ams,
What is the fastest burning/most reliable/stable burning 410bore powder you have pressure tested data for in 3" case w 11/16oz (300gr) load?
I am still working on my 410 pet load, but w296 is not doingnit for me- too low pressure and in my particular case i cant load any heavier shot weight, no stable burn.
i haave only a few loa dmanuals, and the fastest w 11/16oz is HS-6.
Any recommendations appreciated!
C-
