Downloadin 9x19 to 380 Velocity

Postby TEX » Mon Aug 22, 2016 12:08 pm

Have any of you reloaders tried downloading a 9x19 to basically 380 velocity and just enough to get the slide to still cycle. Though of this as a way to ease a new shooter up from a 22rf. A 115 grain moving at about 875 would do the trick, but not sure if it would still cycle the slide. Either that or perhaps one of you knows of a factory 9x19 load that is really slow and soft.

Thanks

I haven't done it, but that's getting really slow for a 115 gr. 9mm. My Lyman Manual (48th edition) shows a load for 115 JHP using 6.8 grains of AA#7 for 871 fps. Be careful with your power choice and don't go below minimums as this is critical with some powders. Once you have a safe load per a reputable reloading manual, just get a recoil spring to fit the load.

I load 124g berry's plated rn/hollow base over 4.2g (?) Of titegroup down to 1000-1020fps. They're the only pill I buy anymore. They work great in every one of my 9mm's (cz p01, g19, sig sp2022) cycle great, work in my suppressor, and they're stupid accurate. I only need 10k more of them!

If you are doing this to graduate new users. Why not go to 380 before 9mm? Also, I try to use full sized or heavier pistols to ease the perceived sensibility to recoil. I find the more rounds fired the more de-synthesized to recoil the shooter becomes.
Of course, a firm grip goes a long way, too.

Many shooters at DPC with racing STI guns (no optics) have almost 0 muzzle flip and a hair trigger go-switch. They modify the pistol by using lighter recoil spring and hammer spring and touch-me-to-fly trigger.

Check out wolff springs as they likely have a lowered power recoil spring that may make function more reliable

When your testing your reduced loads make sure you shoot one at a time and the barrel is clear after each shot. Don't want to get a bullet stuck in the barrel due to reduced velocity.

My favorite load for IDPA with my H&K P7 was a Hornady 124 XTP HP bullet, Winchester WSP primers, and 3.2 gr. of VV N320, OAL 1.125"

It worked fine in the P7, which is unique in that it does not have the tight recoil-impulse window like most pistols. And worked great in IDPA, until a friend chronographed it around 700-725 fps. I always wondered why I had such a hard time knocking down those steel poppers! Okay, OKAY, I load it legal now!

If you purchase a light enough recoil spring, you can shoot as light as you wish. Like the man said, just ensure they are hot enough to clear the barrel reliably.
