I really do think you NEED to look at my picture!
I'm sure they sell swiss in the US?
If you refuse to look at my link, you are just going to confuse me even more than you are!
It's only a link to my own picture, there is no spam on it.

No1 says FFFFg for pistols (4fg)
No2 says FFFg for rifles (3fg)

These are not my words, this is how 'Swiss' sell there powder.
It is the powder I use and I'd like to know how their grading system is working.
You are suggesting I'm using priming powder in my pistols.
Swiss sell a 'Priming Power' No1 FFFFg (4Fg) is sold for pistols.

Please help me to understand what's what.
