The most power I have got out of 10mm is with a Glock 20, aftermarket Bar-Sto barrel for more case support, 1.3", 200 gr, 14.2 gr IMR800X. That is 82% over max published load. 800X meters poorly in my meters, and I have to weight each load.
Blue Dot is an excellent powder, but only 49% above published will fit with 200 gr. There is a flash.
Ramshot Enforcer = AA9 is an excellent powder, but only 19% more than published will fit with 200 gr.
Power Pistol is an exellent powder, and enough will fit to get the pressure up to the point of the primer falling out [in a barrel with good case support], but there is a flash at night.
3N37 will only fit a small amount above published with 200 gr, but it is low flash.
