Problem with 9MM Reloads

[ourway77]

I have been reloading for 50 or more years I'm have a problem chambering 9MM reloads in my Glock 17 I FLR them check over all mesurment Upon seating the bullet I check with a gauge and they drop right in but I load a clip and the first chambers fine and the rest I have to bang the rear of the slide with the palm of my hand then they will fire Primers flush Thanks Lou

Hey Lou, have you extracted one unfired round to see if the bullets are being deformed during the cycling into the chamber. 9mm, and all semi-auto for that matter, can be tricky when it comes to stripping one off of the magazine and pushing it into the chamber. Too much recoil, not enough recoil, bullet shape, recoil spring strength, slide weight, hammer spring strength, slide to frame lubrication and fit, all come into play. Glocks are known for eating anything, well as you know just almost anything, but they can still choke if any of the above doesn't line up.

Are all rounds the same head stamp and are you checking them with a case gauge ? I had a problem with my 45 and a custom barrel and I wasn't crimping them enough to chamber, had to bump the slide shut every time . Pull the barrel and drop your loaded rounds in the barrel to check them , if it fits there you have a feed problem.

Could be the glock bulge.

Have you tried another magazine?

OAL to long. Taper crimp more.

I had some that did that also, seating the bullet a few thousandths deeper cured the problem. I wasn't at max on the powder charge so nothing besides bullet seating depth needed to be changed. Different bullets by different manufacturers usually have different profiles even though the weight is the same. If you're using range brass, it could be that the rear portion of the case above the extractor groove isn't being completely sized enough. I use a dedicated shell holder for each die set, with the press ram at it's highest point, screw the die down until it touches the shell holder then back it off about 1/16th to 1/8th of a turn a set the lock ring.

If none of the advice above helps get a Lee factory crimp die. It will remove most feeding problems and ammo should chamber fine if cases are not too long. Hope you get this sorted out.

You should be using a taper crimp die as the last operation, separate from the seating operation. Just remove the barrel from your Glock and insert a finished round into the chamber. It should drop all the way in by just gravity. If not adjust the taper crimp until it does.

Thanks everyone great information I do check case length, try to stay with same brand. If any Glock bulged cases I discard them I will try seating the bullets deeper as suggested. Goin to buy a Lee taper crimp die as suggested

"Glock Bulges" are not a problem with 9mm. Glock "bulges" are a problem with the .40 S&W because of its high pressure.

We reload around 5000 9mm per year. We purchase brass from a range and reload them on a Dillon 550 with Dillon dies. Never had an issue with 9mm "Glock Bulges".

With .40 S&W I push them through a Lee Factory Crimp Die to remove the "Glock Bulge".

Send those “discards” to me! I’ll fix them! I bought a push thru die when I bought a Glock 35 in 40SW. It works great!

roll size the brass before full length sizing

roll size the brass before full length sizing

Huh????

Ourway,

My advice is to discard the case gauge.
Strip your barrel out of your Glock(takes all of 30 seconds) and do a plunk test with your barrel.
I was getting exactly as you described. COAL was too long. Within book, and gauge, but not chamber.
Best of luck!

9mm Glocks have a tendacy to act funny if the bullet is not seated deep enough. Sometimes only .002 to .003 will make the difference in feeding & chambering properly. As mentioned the book and gauge will not tell you the truth every time.

Sounds like a load powerful enough to get the bolt back far enough to strip a round off the clip - but not far back enough to fully load the mainspring. I say add a bit of powder unless you are at the top of the manual and the problem will likely go away. I'm guessing you are not there.

If you get the LEE taper crimp die, get the one with the carbide ring at the bottom of the die. This really does "iron out" little discrepancies left over from the loading process. Trash that LEE lock ring and put a good quality split lock ring on and set it. You want repeatability with your ammo, this goes a long way towards achieving that.

Another happy reloader with the Lee factory taper crimp die. Easy to use and just works.
