The above was one item that I extracted from a rather rambling reply. For your 90 gr, QL data would be better if I had bullet length and desired COAL, but I will just use a Lee 93 RN and default COL for now. I found info said to come from Accurate folks that 100NF in pistols will have a max allowed charge around 10% below the original Nitro 100. QL only has the original.
This powder has a very fast burn rate and is pretty "fluffy" taking up a good bit of case volume. Predicted velocities seemed low to me right up to the point of approaching max allowed pressure. With the small range of acceptable charges and the old vs new version stuff, I am not sure I would use it the 32 short without pressure tested load data.
I then ran looking for "best powders" and only gained 30 to 40 fps with Titegroup being one of the better choices that is also known to be not so to hard to find.

For 32 long and a Lee 93, Nitro 100 seems more useable (again, use say 90% of the below charges with 100NF as approximations). Also note that the QL barrel length and cylinder gap stuff affects velocities as previously described.
