Here's the load data from inceptor that I'm starting with, meant to attach to the OP, but here it is, in case anyone else is interested. Sorry I had to cut it in half to get under 250k.

I just checked, Midway still has the 90gr for sale if anyone else is interested in grabbing a box before they're gone for good.

Thanks for the info guys, glad to hear from someone who actually reloaded these! I'll let you know what I get, but I guess I won't put too much time into working up a perfect load, since I only have a few hundred. I'll probably load five at a time until I find something reliable and leave it at that. Shadow, thanks for the first hand comparison between autocomp and CFE.

Hey everybody, newb here. I've been reloading for years and finally got the pistol I've been dreaming about, in a caliber that's worth it(SA 1911range officer)! I got a box of ARX bullets on a whim and the only load data I can find is from the manufacturer, and uses autocomp, which the reloading shop out here straight up refuses to order for me. I have plenty of CFE pistol which is pretty close as far as burn rate goes. Has anyone loaded ARX's? With CFE? Any suggestions on working up a minimum load? I know it's kinda against the whole point of 10mm to run a 90gr round, but I want to get my wife comfortable with the new baby thanks!
