I set down, getting ready for my range session tomorrow. I just bought another pound of triple 7. I was not paying attention. I picked up 3f and not 2f (minor mistake lol)

do i need to drop my charge amounts for 3f any or can I use the same amounts as 2f? I am only using 75grs of triple 7 2f.

I have enough 2f for 2 maybe 3 ranges sessions but I am feeding two guns with it.
