I would call the bullet maker and ask if the have a recommended col. they might be able to get you in the ballpark.
aside from that make 1 dummy round. seat the bullet to 1.160 and start working down until you get a clean plunk, using your chamber as a gauge.
Hodgdon for 124g lead shows 3.4start to 3.8gmax at around 1012fps at max
my rule with lead, coated, and plated bullets is, as long as your staying under about 1250fps i used jacketed data. YMMV
#2 is an awful fast burning powder for heavier 9mm. It might be worth looking into other powder choices unless your just looking for a way to get rid of some #2. I have used HP-38, Power Pistol, CFE Pistol, #7, Clays in 9mm. #7 in my experience, likes heavier bullets, 124g and up and used more powder to get the job done. The rest all worked well for everything I have tried.
