It is a powder that runs best near the upper pressure end.
It does have WSF qualities but burns cleaner when loaded up properly. Actually it burns real clean in 40's in the middle charge weight.
I agree just because you can load it doesn't mean it will act like a factory load in every caliber. But My 9mm's and 40's feel just like factory rounds.
As far as burn rate, faster burn rate generally translates into lower velocities and higher pressures than some of the slower burning powders. There are a couple of exceptions to this rule. Red Dot being one of them. Red Dot is a faster powder but produces higher velocities than most fast powders. Higher velocities translate to higher recoil.
IMO you could use a different powder. Clays might be your best bet if you can get it. Also your loading max charge. If you have little to no powder resources at the time (like most of us)Drop it down to start weight (2.7) and see if that helps first. Oh and is your OAL .978" range? You drop below that and the pressure will pick up very quickly in 32acp.
