Although GSSF doesn't have a PF requirement, I wanted one single (9 mil) load for GSSF, IDPA, and Steel. The 320 load I use has a PF of ~130 to satisfy IDPA requirements and is a wonderfully soft-shooter in every stock Glock I own. (which is all
of Glock's 9 mils).
I also think that the top two powders for this requirement are TG and 320 - both rather high in the burn rate table, and both having a limited load range and both somewhat susceptible to user error.
