[Barnacle Brad]

I have a new container of Swiss 1 1/2 FG powder for my trapdoor rifle and wonder if there is any reason not to use it? I don't have a powder press so would not be using very hot load (compressed loads).

All the trapdoor loads I see use 2F or 3F. New to loading black powder, but have loaded Triple Seven and Smokeless for this a bunch.

Any recommendations or thoughts appreciated.

1884 Springfield trapdoor rifle
45-70
starline brass (unmodified primer pockets)
CCI 200 large rifle primers
58gr Swiss 1 1/2 FG (?) (this is the weight of powder volume to bottom of bullet 3/32 or so above fully seated bullet depth)

Thanks!
