This is a follow-up to my thread on reloading 9mm Luger (9X19).
Link to Archived Thread I finally got to the range to do some chronographing. Here are the results. 125gr RNL, 3.4 gr W231, WSP primer, 1.135" OAL Avg = 787 fps, SD = 14, n = 5 4.15 gr W231, otherwise same as above Avg = 905 fps, SD = 11, n = 5 4.5 gr W231, otherwise same as above Avg = 953 fps, SD = 14, n = 5 These were fired from a short barreled (~3") handgun, Star Firestar Plus. It's a great little handgun (13+1 capacity in 9mm) made by a company that, for some reason unknown to me, went out of business. As a result, they are inexpensive to purchase and parts and magazines are readily available. This is no cheap, piece of crap. It's the real deal.

I'm assuming your OAL is wrong?
If it's not, what are you loading these in that puts them beyond SAAMI max OAL for 9mm, and what mag is feeding them properly? |

OAL is pretty forgiving in 9mm. I routinely load to 1.125 for my Glock using 115gn plated bullets. Just check them in the chamber to make sure they fit. 9mm indexes off the case mouth not the bullet.
ETA: I should add that seating 9mm too short can raise chamber pressure when using fast powders. I should have stated that OAL is pretty forgiving in 9mm when seating long. |

My standard 9mm load is 4.6 gr of WW231 behind a 115 gr jacketed bullet.
Beretta Model 92FS that's a 5" bbl 115 gr JHP Federal primer avg vel 1091 fps SD 14.5 |

I got these bullets from someone who shot a 92FS in competitions. My 9mm handgun is intended for self defense. These RNL's don't work particularly well in that role but I will load them up to self defense ammo levels and use them for practice. In that role, they have a place and will save me a lot of cash. Surely, I do have a lot of them and factory ammo is too expensive to use thousands of rounds for practice. |

You're low by a fair amount if looking for SD type ammo velocities..as it is, none of those rounds even make min. USPSA or IDPA power factor of 125(wt. * vel / 1000). I'd expect most SD 9mm to be around a PF of 140 and higher, although its worth confirming chrono-ing your SD load of choice. |

Basically, I was so happy to get the data I now have, I forgot to chrono some factory fodder. The 124 gr Federal ammo is supposed to get to 1120 fps but I haven't chronographed any. |

I use Power Pistol if I want to simulate SD loads. They are hot.

I just saw you're shooting out of a shorter barrel. Will be interesting to see what kind of velocity you're getting with the 3" barrel, as well. |
