Hi everyone, I thought a few people might find this a bit interesting, or maybe even useful. Not too long ago, I bought myself a 9mm Kel-Tec Sub2000 as a little fun plinking gun. Before I bought the gun, I got into handloading, and had already worked up a 124 grain load for my pistols using HP-38. Firing it from the Sub2000, I didn't see much of an energy difference. When I started running low on HP-38, I decided to pick up a pound of CFE Pistol. I worked up a load for my handgun, and the powder worked great. I thought it was fairly clean burning and really did reduce copper fouling after a few hundred rounds. So I thought it would be fun to try out in the Sub2000. Well, when I loaded these same rounds into the Sub2000 and fired the first shot, there was a HUGE difference. The report was significantly louder, the recoil was significantly more than my standard HP-38 loads, and the projectile was hitting the steel with much more force. After reading Hodgdon's burn rate chart, I quickly realized why this was the case. CFE Pistol is a fairly slow burning powder, and this must be what was contributing to the significant boost in energy. I stepped back to around 75 yards, and to my amazement, I was able to ring the steel very easily. The projectile was reaching the target much, much faster than my standard loads. The steel plate was also reacting as if I had shot it from 10 yards with my CZ. I unfortunately don't have a chronograph yet, but I'm convinced these rounds are leaving that 16" barrel around 1500-1600 fps (124 grain projectile). This puts the energy on par with that of a 125 grain .357 magnum cartridge, if that velocity is true. Either way, it's still flying a good bit faster than normal, and shooting from a distance is much easier. I figured some of you might find this info interesting. If any of you have a 16" barreled 9mm carbine, and some CFE pistol, try it out! You might be surprised. Also, if you try this and have a chronograph, let me know what kind of velocities you get! It makes the gun significantly more fun to fire.
