I was just wondering if anyone has used this powder for reloading 10mm? My Hornady 8th edition says 8.8 grains max which will produce 1150 FPS with a 180 grain bullet, that is not much more than a 40 S&W. I was wondering if anyone has used the 4756 and got higher velocities with a 180 grain bullet? I am using 180 grn FMJ and loading 40 S&W as well. I am wanting around 1250 FPS with the 10mm and 1100-1150 with the 40 S&W if possible, Any help on either of these rounds would be great. Thanks
