Problem with 124gr FP Load - xtreme bullets

[JackRydden224]

Hey guys I loaded up some 124gr FP 9mm rounds at 1.08" OAL which chambers the first round just fine when I rack the slide but the slide would not fully return to battery after the first round ejects. The rounds fit Dillon's case gauge just fine. What are some possible issues? I'm thinking maybe I'm loading them too long? The bullets are from xtreme

Sort of hard to answer when we don't know which gun you're feeding them through or which powder, and quantity, you're using.

When I last loaded the Xtreme 124gr FP, I was loading them about the same length for my M&P9...for which I was loading the 124gr RN at 1.140"...and it fed fine for several thousand rounds

At 1.08" I don't think they are loaded to long, it's kinda on the short side...
Take out your barrel and see if the drop in ok. You might have a sizing problem even though it fits the case gauge.

I load the same bullet, mine are 1.12" over 4.8 grains of BE-86 for a 9mm SSA Range Officer. Never had a problem

I'm thinking too short as well.

Sorry for the lack of details. I'm loading 3.9 grains of 700x. The gun was a Walther PPQ M2. The OAL range for 124FP is all over the place and many folks say their loads work just fine. I'm going to manually cycle through a mag and see what happens.

EDIT: I tried to hand cycle the rounds. The first round would chamber as long as I cycle it correctly but I cannot get it to eject without grabbing the slide and repeatedly striking the grip. At this point I think my sizing is off.

Have you tried factory ammo in the gun? The gun could be the problem not your reloads.

Try putting in a brass case in the barrel. One that has been sized. My guess is that there might be a slight bulge at the base preventing it from fully seating.

I have. The gun has more than 1,000 rounds though it without a hiccup. It shoots my 115gr reloads just fine.

I'll try that out. Thanks

Remember that the gun is designed to eject empty cases. Some guns will not freely eject a full round. Take a factory round and see how they eject when hand cycled, then compare to your loads.

My PPQ M2 has a very short throat (like all PPQs), and I load 124 gn coated SNS Casting bullets to 1.060 (yes 1.060, not a typo), which is short, but that bullet's profile calls for it. I've gone through maybe 2000-2500 of them, not a single misfeed. The FIRST time I loaded this bullet, I set it to my normal 1.140, which I used for a different bullet and I had to use a squib rod to get the round out of the barrel after racking it. The PPQ has a stepped AND short throat. So actually 1.080 may not be too short, depending on the ogive/profile of your bullet!

Load up a few dummy rounds at shorter OAL to see if that's it. Also check your crimp. I don't recall the exact number, but I was thinking .378 diameter at the case mouth was about the right crimp, but don't quote me on that (or the other shorter OAL numbers), I'm just explaining my own experience with reloading for the PPQ.

SAAMI specs for the 9x19 are Min of 1.000" to Max of 1.169".

Loading manuals list whatever OAL was used to collect the data they publish for a given load.

Neither source is Cast in Stone. They are references.

Only an individual firearm can decide what will/won't work in it. Depending on chamber dia. and depth, feed ramp contour and angle, mag lips, mag lenght, etc, etc.

Chamber gages are typically cut to min spec for reliability in all SAAMI spec chambers.

Here's the catch. Words like, typically work, should work, can work, generally work, usually work, just don't cut it when you get a picky eater.

Only "WILL work" matters on the firing line.

Time to do some testing.

I have a similar post going with Berry's 124gr HBFP. My gun is a shield and at 1.100 it seems to feed and cycle from the mag with a dummy round. I can load 115gr RN at 1.150 and it will feed and fire fine.
I haven't had time to load a few of the FP's and shoot them yet, but I will try it at 1.100 with a start charge and see.

[JackRydden224]

I hand cycled the rounds through every other gun I have in 9mm they all worked fine. I never thought the PPQ would be the problem. It's my only polymore pistol so I thought it would have the widest tolerance. Who would have thought.

Thanks for the info Lead Waster

So the gun was the problem.
