Everywhere ive read,they say 2400 wont work in 10mm. Proved that as false today.
200gr at 1220fps,and 186hp at 1340.plenty of speed,es numbers are a little large,but shot pretty good groups.
Dont be afraid of good ol 2400,in the10!

How many grains? I ran some numbers thru GRT and to get the velocity you got with 200 gr bullet, you are right at the max allowable pressure for the chamber. BE CAREFUL!!!

I have used it but it would give me smiles in the MechTech so I prefer to to have ta worry so looked for other powders. For me PowerPistol is amazing in the 10. My 160hp can hit 1400+ my 200 can pass 1300 but I dont load either that hot. 1250 / 200 is a good shooter! Also the Lee 175 @ 1350 is a smoking one hole shooter for me!! ZERO case head expansion issues even in the blow back Mech tech! (I hesitate to tell the 16" velocity ;))
