I'm looking for info on a 9mm load. I've loaded extensively for rifle calibers, but this is my first foray into handloading pistol calibers, so bear with me  .
I traded into a ton of Rainier 115g HP projectiles and mystery 115g pulled projectiles (no manufacturer listed on the sealed box, other then that they are pulled projectiles). The seller advised me to "load them as though they were lead projectiles" (published load minus 10%). Does anyone know why he would advise against standard 115 grain loads with these projectiles? They appear to be jacketed and I cannot find any documentation online that advises against standard loads with the Rainier projectiles. The plan is to use these as plinking rounds, so no need to load anything super hot. I intend to start at 4.0g Titegroup and work my way up to 4.7, 0.10 at a time. Primers are CCI 550s, and I'm planning about a 1.1" OAL. Weapon is a G19. I just realized that CCI 550s are magnum small pistol primers, so follow on question - are they okay to use for 9mm? Any thoughts or advise? Am I increasing the likelyhood of turning my Glock into a hand grenade with this plan  ?

If they are pulled, jacketed bullets I'd load them as jacketed bullets.
The Rainier are plated and need to be loaded as such. Get the chrony out and create a different load for each of the two bullet types you have. Try to get the velocity for each load up to WWB spec, which is 1150 to 1175 FPS. Rainier has loading data on their website. Edited to add: sure you can use 550s in 9mm but I'd get regular pistol primers instead, you are already designing two loads from scratch, why complicate matters. And yet another frigging Edited to add: Don't hotrod your 9mm loads on brass that has been fired a bunch or you'll blow the mag out the bottom of your Glock like I did. 
It didn't hurt anything though. |

Thanks for the two responses. I'm going to start working up a load for the Rainier HPs before I move onto the pulled FMJs. Given what I found on Google about using the magnum primers, I've decided to be conservative. Starting at 3.7g Titegroup, I loaded 10 rounds at each 1/10th of a grain interval up through 4.3, OAL1.125". I'm debating whether its worth pushing it to 4.7 - I think I might hold off at 4.5 just to be on the safe side.
When you say: Quoted:

Bullets like Rainier and Berry's are plated, not a FMJ projectile. The difference is that a fmj is usually pure lead, swaged into a copper jacket. A plated bullet will be easy to spot, since it's fully encased with no seams. These are plated, I believe, with and electric plating process. Plating is usually very thin, so the slug is pretty soft and will act a lot like a lead projectile, but still has the smooth bearing surface of copper. Because of this i consider plated projectiles to be right in the middle between jacketed and lead, if plated info is not available. For example, let's say the max load for lead is 4.0gr and the max for jacketed is 4.6, I would personally split the difference and put it at 4.3gr. This is just my personal opinion, but it worked for me.
Now I only shoot Precision Delta slugs, since they're so darn cheap.  I'm done with plated.

| you can use the magnum primers with those if that is what you have. no need to go out and buy them specifically for reloading these. but remember, magnum primers can add anywhere from 20 to 50 fps to your velocity and also increase the chamber/case pressure so it is advised to take your reloading data and back it down a bit and start there when using magnum primers. |

I just want to emphasize in the above statement that magnum primers CAN (but won't NECESSARILY) increase velocity and pressure in any given load. Calling a primer a "magnum" primer implies it's more powerful, and this may be true, but there's no standardization on whether the primer is really any different in any substantial way. As with any change in components from an established load (yours or a recommended load in a manual), work the load up carefully. |

So, I hit the range today and tried 10 rounds of each load from 3.7g to 4.6g Titegroup. I didn't see any signs of overpressure at all - however loads under 3.9g didn't cycle the slide reliably. I saw a fairly significant degradation of accuracy at the loads above 4.4. I think 4.3g is where I want to be, which is consistent with the advice I was given, 10% under the max load (4.8g).
Thanks to everyone who provided input. |

Glocks can be sprung tight and usually don't like minimum loads. I'm loading 9mm for a G17, 19, and 26. Another thing I have found is a few feeding issues with the 1.1" COAL with 115 grain fmj. I think I'm right at 1.21" COAL for the 115 and it worked that out. I haven't tried any HP 115 grain though.
Sounds like you have a load worked out. I think I have found HS-6 works well for me. Fills the case nicely, burns fairly clean, and is accurate enough for what I'm doing with it. |
