If you have a need to make IPSC type Minor Pf, then a chronograph will be necessary. 4.5 grains may be close to the 125 Pf minimum. (Hornady suggests 1,000 fps at that charge with a 4" barrel).
FWIW, Speer is the only manual that tends to list max loads that I could never get to (rifle stuff and none recently). I would be a bit leery of their max charge unless approached cautiously. Less so on the others.
