gnoahhh
I'm similar but diff powder.
I ONLY ever bought ONE (1) pound of 3031. It is too fast burning for any cartridge I ever loaded.
I bought and used several pounds of 4320 for my 35 Whelen. My understanding of its burning rate is
between 4064 - 4320 - 4350. I have wondered if I should have tried to find out how close to 4350 it is/was.
Oh Well. I'm sad to see it go but I won't have a void.
