Range data for 357 Sig, 10mm & 40 cal
I found info in reloading manuals and Hodgdon/Accurate/Alliant websites, so these I'll not feel bad about sharing. (Legit data)
8.3 grains of CFE was able to push a 115 Hornady projectile to 1391 FPS. A load I will continue to use.
11 grains of AA#7 got the same 115 JHP to 1317 FPS and was just OK in my notes.
8.2 grains of BE-86 and a 125 grain Montana Gold was another keeper at 1336 FPS.
I started shooting 357 and 10mm because I was after a "fast" bullet. In 10mm and 40 S&W, I think I have found what I was looking for! So much so, that I backed down the 10mm load!
I used Longshot to get a 155 grain Montana Gold 10mm projectile to over 1540 FPS! (OUTLAW ROUND> NOT LISTED OFFICIALLY ANYWHERE) I will continue to shoot a reduced version of this load at 1477 FPS.
Hodgdon also listed 8 grains of Longshot with a 180 grain 40 S&W and it went 1175 FPS out of my P226!
Longshot is a very powerful powder that I will continue to use with large/heavy bullets.
Shoot safe my brothers!

LONGSHOT is among my very favorite powders. It get top velocities in 357 SIG, 40 SW, and 10mm and good velocities in the other handgun calibers.
It does this without making to big of a mess in your gun and low muzzle flash and smoke. At least compared to Blue Dot.
I have loaded a few hundred Hornady HAP 180g bullets with the top Hodgdon Data in the 40SW to 1160 fps and it will wake you up to be sure!
I like the 180 @ about 1100 fps, it's down from the max load and accurate and very powerful. Once I got this load worked out, I kind of lost interest in the 10mm because there are just so many more nice guns in 40 than 10mm and most of the 40 bullets come apart at 10mm velocity anyways.
