9MM Loads

Greetings,
I am trying to find the right combination for reloading some 9mm rounds. Here is what I have.
Bullseye: 4.5gr
Winchester 115gr FMJ with hollow base
Winchester Small Pistol Primers
OAL: 1.169

I am unable to get the rounds to eject. The slide does not fully cycle.

Here is what I have loaded now but have not yet shot.
I have reduced the OAL to 1.145
Powder to 4.6gr.
Everything else is the same.

Thanks
Bryan

RE: 9MM Loads

Thats strange, what type of gun? I've used 4.5gr with Berrys Plated with little/no crimp with no problems out of my ruger sr9. They were not hollow base so if you are using hollow base this should make your combustion area larger within the case. If youre using FMJ, I suggest using Blue Dot with heavy crimp. Works well in the high pressure cases like 9mm and .357mag for me and throws some flames out of my 2in snub. I use Bullseye for the .38spl and have used it some since I switched over to plated bullets since you can't put a real crimp on them and bulleye is fast burning.

Overall the slower powders are more efficent if you have the barrel lenght/crimp ability but I have used 4.5gr of Bullseye and 115s with no problem. Your shortening of the rounds should increase pressure so maybe that will help. The Alliant website is giving an overall length of 1.125 so maybe you should check their website for yourself and use that recipe. I usually keep mine around 1.153 since thats what the Federals have measured out to so maybe you just need more pressure to cycle the round with that extra combustion space.

I'm using Accurate #5 at 5.4 gr. w/Barnes cast copper plated 115gr round nose and CCI #550 small pistol primers for 1023 fps. OAL is 1.13"/28.9mm.

Haven't had any misfeeds or malfunctions firing in a Browning Hi-Power and a Taurus PT709 Slim.

RE: 9MM Loads

I'm not sure what type of pistol youre shooting these out of, but one culplrit could be the weight of recoil spring. If you have one, try one with a lighter weight

My favorite 9mm recipe is 4.0gr of Titegroup w/ 124gr @ 1.160, slight to no crimp, have yet to experience a single problem with it out of the 10,000+ Ive made.

RE: 9MM Loads

Am loading 115grn. Blackhawkes with Winchester WST 4.6 grn. in Winchester cases and standard recoil spring and are a sweet load with no problems at all. Have just gone to using small rifle primers and all is good, no good in revolvers as firing pin does not hit hard enough. ps. Blackhawkes are fully molly coated and can be purchased from Australia but cost unknown. www.HRBC.com.au

RE: 9MM Loads

I have used 4.8 gr of 231, 4.9 gr of Universal, and 4.5 gr of Titegroup for 115 gr bullet in 9mm. All function very well and are accurate. I load to 1.120" col. Your load should work, check your gun...did you change the mainspring? Any mods? The load you are using is a standard Bullseye load.
