This is from Hodgdon Load Data Center. USE AT YOUR OWN RISK!!!!
I use the following load data;
125gr Hornady HAP, TiteGroup, bullet dia. .356, COAL 1.069", 2.8 gr of powder, 816 FPS, 27,000PSI, up to 3.2 gr of powder, 930 FPS, 33,700 PSI
or
125gr SIE FMJ, bullet dia. .355", COAL 1.090", 4.1gr of powder, 1,069 FPS, 27,300 CUP, to 4.4gr of powder, 1.136 FPS, COP 30,600
I start at the low end and slowly work up because the range from min to max is .4 gr for the first load and .3 for the second load. I also load as long as possible to fit the magazine and barrel chamber.

As for why they do not list more loads is because they do not have safe data for other loads, just my thought.
