[Glock Pmag 17 rd failure]

The blue bullets would drop in, but would not spin, at about 1.10 in the Alpha wolf.  Someone suggested it was just the profile of that bullet, and not to worry too much, as long as it dropped in.  Well, I think that left the bullet right at the rifling, and on one occasion the gun locked up at the 'unload and show clear' command...took a bit of a kung fu chop to get it open. The bullet had a big cut on it, just above the case.  If I load down to like 1.05, they drop, spin, and fire just fine in the Alpha.  And as I said, the factory barrel plunks and spins all the way out to 1.14, which is as long as I've tried.

That's really long.....

I'm running my reloads 1.06 to 1.07, regardless of projectile weight from 115 gr up to 147 gr.

 

What would be the advantage to running this short?  I picked 1.160 based on a combination of the plunk test (this was close to max on my Alpha Wolf barrel with the Xtreme 147) and some different reloading data.  It proved to be accurate and hit my PF target, so I didn't fool with it, and i got the impression that loading as long (close to the rifling) as possible was a good plan.   Am I missing out on something?

Now blue bullets in my alpha wolf have to be loaded that short in order to pass the plunk. On the factory glock barrel, I can go much longer, and usually go about 1.14.

My loads are right at 1.160, and my problem seems to be more the mag giving up rounds too easy, vs something hanging up.

Thanks for all the input  it was brass cased reloads that I had the issue with

 I use magpul mags for my 300blk ar, super and subsonic without issue, so I don't think it's a bad product  that said, the metal liner in the factory mag does seem superior.  

picked up 2 factory packaged glock brand mags at the gun show for $20 each, so now I have 4 for primaries. as others said, I'll keep the pmag for practice, and see if I have any other issues with it

Hi All,

I tried searching on this, but didn't find exactly what I was looking for.  last night, in a local steel challenge match, I had what I think was a 17rd Pmag failure in my glock 34..  I keep 3 mags loaded for these events, 2 OEM glock 17 rounders, which are pretty much all I actually end up putting in the gun, and one 17 rd pmag as an emergency spare.  Since most stages are usually only 18-24 rounds, I have never used the pmag (other than in practice) until last night.

One one stage, they had 2 mandatory reloads, so I had to use the pmag.  It was filled with 17rds of my go to 147gr load, and on 2nd shot, the gun locked up hard.  I wasn't able to rack the slide even, until I ejected the mag, at which point one round went into battery, and another fell out loose, with the mag.  When I picked the mag up after the stage, the next round in line appeared to be trying to sneak out by going straight up through the feedlips, vs. out the front as per normal.

When I got home, I loaded up the pmag with 17 rds again, and with only slight upward pressure on the nose of the bullet, was able to sort of pop it out, straight up, out of the mag.  I tried the same test with the factory mag, and could not make this happen...not surprising, with the metal reinforcement of the OEM.  I'm thinking that since the Pmag doesn't see much use, the spring is still really tight, and when loaded full, was putting a lot of upwards pressure on the rounds, which caused a round to 'pop out'.  Has anyone else seen this before?  I figure one solution would be to load the mag up, and leave it that way to break the spring in, but I think the better plan is to just stick to OEM mags...I didn't buy the pmag to save money, but rather because it was all the shop I was in had.  

Or maybe there is something else I'm missing?  The gun is basically stock, with the exception of a glockmeister stainless guide rod and 15# ismi spring. Loads are 135-ish pf.  I had maybe 1 or 2 FTE's out of probably 1000 rounds with the stock spring, and this is the first issue with the 15#, but it looks to be pretty clearly a mag issue.

[Ready to declare titegroup 'my powder of choice' and move on...or am I?]

First wanted to say hi, and thank all of you for all the great advice, comments, and such I've been able to find on these forums as I've been lurking for the last few months.

I've come up with a handload that I really like:  3.2gr of Titegroup under xtreme 147's with wsp's at about 1.16 oal make between 135 and 137pf, depending on the day / chrono (single digit sd and low double ed),   Functions my gen 3 g34 with stock springs just fine, and is more accurate than I am.  

I'm not new to reloading, but new to 9mm...oh, and I like to try different stuff.  When I worked up my loads for my 300 blackout, I started with 7 powders, finally settling on 2, one for supers and one for subs.  With 9mm, I have only tried 2, Titegroup and True Blue.  Both worked well, but the lower charge and lower cost of TG settled it.  I have not seen any pressure signs, nor does the gun seem unusually dirty.  The barrel does get hot, and I expected that from a double base (I use Lil gun in my 300, and it heats up good too), but so far, it doesn't seem to matter. I've also used 147(ish) rn from Blue Bullets over 2.9gr...my lone wolf barrel doesn't really like them, but I think the factory barrel will, but at only about 1.5 cents less than the xtremes, I just haven't looked into them further.

Prior to the election, I was all set to run out and buy a bunch of TG, but there was none to be had.  Now that things are returning to normal, I can get TG for $20-$22 per pound in a couple of places locally, or less if I buy 4 or 8 pounds.  But I can also find N320 locally, and the posts about Prima V sure look interesting, but I'm not sure what I'm looking for.  With the 300, I had stuff like rifle function (its an 8" suppressed AR) and report at stake (faster powders are quieter, but tend to not function as well), so there were clear advantages to some powders over others.  With 9mm, I feel like I've achieved all I need to, and should spend my time loading and shooting, not researching and scouring...

So I ask you all...can I just ride off into the TG sunset?
