Can someone with quick load help? Almost kaboomed my Glock.

[sammy]

Good evening everyone,

This afternoon I went to the range to work up a 124g Gold Dot. These are pulled from American Reloading. I started with 5 grains of BE86 and worked up tp 6 grains. Book max is 5.9 grains. Shooting a Glock 19 and 34, both with KKM barrels.

Here are my results. Average velocities as follows.

5.0 grains G19 981 G34 1048
5.2 grains G19 1052 G34 1092
5.4 grains G19 1083 G34 1108
5.7 grains G19 1100 G34 1185
6 grains G19 1163 G34 1191

The last shot with the G19 on the 6.0 grain load gave me 1383fps. Major power factor if I am correct. Stout recoil and pierced the primer.

I just spent the last 2 hours weighing the 2900 remaining bullets. Found 5-115 grain bullets in the box I was working from and one in another box. Nothing over 125 grains.

Can someone with quick load run a 147g JHP with 6 grains of BE86 in a 4" barrel? I would be grateful.
Not sure what happened. Loading on a Dillon 650. Is it possible a 147g bullet made it's way in there to give such high velocity and pressures? I really can't think of anything else that would cause this.




Thanks!! Sammy

No way a 147 got pushed out at 1384, what it takes for that to happen would probably rupture the case. Even a 124 at that speed is very darn hot, +p territory. Perhaps an overcharge or bullet setback?

Seating depth is crucial in 9. Sorry, no QL data here, but just a little note that pressures go up quickly when the bullet is just a little deeper than it was during load development. Good luck.

Sounds like our had some bullet setback. What is your OAL for your load?

Alliant Powder has a webpage.

Yes these are American Reloading pulls. They look very good and measure correct.

Measured 1.15oal.

I'm also thinking setback. Makes me want to discard them.

Sammy,

I doubt it was a 147 gr that left that barrel at nearly 1400 fps. If that's the case, you're very lucky to still have whatever was behind the slide at that moment. For the record, given the volume of 6 grains of any powder I know, the length of a 147 projo, and all of the other 9mm bits and pieces, I would say that is too much powder absolutely period. But I do not use BE86...I've used TiteGroup under 147 gr. I had 3.0 grains under them and got about 1000 fps. Soft shooting and very accurate. This leads me to believe that this was NOT a 147 gr. BTW...I would not recommend 6 grains of any powder under a 147 gr bullet even for testing in any 9mm.

A 147 gr projo is visibly different than a 115/124 gr one, so keep an eye out.

I agree with bullet setback if it were one or two that got that velocity. If they are pulled, then I would also agree that the bases of the bullets might be just a smidge narrower than the standard width due to having already been seated once, so it's conceivable that it was a little loose and the tension between bullet and case wasn't exactly where it needed to be allowing the bullet to either be pushed back during loading for example or as the weapon discharges, the inertia can seat the bullet a bit deeper into the case.

Here's something I would try: take a 9mm casing that you intend to reload. Resize it and deprime it as you normally would. Do not prime it or use powder. Put it in the press and seat one of these pulled bullets. Do it exactly as you did it for the others. Make 3 or 4 of them. Now...see if you can, with your fingers only and with no mechanical assistance, push or pull the bullet in or out of the casing, even just a little. If you can, then I bet heavily on setback and you may need to consider a mitigation; perhaps a slight crimp with less powder. For reference purposes, get 5 or 6 factory manufactured 9mm cartridges and do the same push/pull test just for a sense of what a good amount of tension on the bullet/casing is.

Can someone with quick load run a 147g JHP with 6 grains of BE86 in a 4" barrel?

My Quickoad does not have be86 in the powder library.
If you can find me a powder profile data block for be86, i can add it to my library and run a simulation for you.

A quickload powder profile is a simple line of text with values for a specific powder that are formatted like this:
"Alliant POWER PISTOL ","5150","1.2070","1.630","2.1300","0.1500","0 .250 ","1.1762","0.730","","","","","","","","","", ""," ALPowPistol.jpg",""

Here is your simulation using bullseye instead:

Cartridge          : 9 mm NATO (9 x 19 mm) EPVAT Piezo
Bullet             : .355, 147, Hornady HPBT XTP 35580
Useable Case Capaci: 7.332 grain H2O = 0.476 cm³
Cartridge O.A.L. L6: 1.150 inch = 29.21 mm
Barrel Length      : 4.0 inch = 101.6 mm
