Hollow points not feeding in G26\’s but feeding in G17\’s

[Joe in Missouri]

I could really use some input and will make this short and to the point:

I just made up some 124gn hollow points to try out

https://www.rmrbullets.com/shop/bullets/pistol/9mm-355/9mm-124-gr-rmr-jhp-mpr-nuke/

They cycle well in 2 different gen 4 G17\’s.
In both a gen 4 and gen 3 G26 they don\’t want to feed in.
I get a bang and then the next round does not chamber.
Usually slanted up toward the chamber with the slide not closed.

Sorry if I left anything out.

What is your load data?

[Joe in Missouri]

I did 2 different loads:

5.5 gn of RS Silouette with an OAL of 1.160\” ish — crony at about 1000 FPS

5.0 gn of RS Siloutte with an OAL of 1.155\” ish — crony at about 900+ FPS

both used CCI #500 small pistol primers.

I can\’t edit above so:
I also noted that some of the cartridges were tight in the case gauge at the rim end.
(not sure why – perhaps I don\’t know how to crimp these correctly)
I don\’t think that was an issue (at least it was not with the G17)
and in the G26 the cartridge did not even get that far into the chamber.

The load seems pretty warm.

Does it seem like the cartridge is not being fed from the magazine quick enough for the slide to catch it?

Or, is it not feeding up the ramp and getting hung in the chamber?

[Joe in Missouri]

I probably need to go shoot some more an observe, but for now I will say the the cartridge is not being fed quickly enough for the slide to catch it.

Not sure what not feeding up the ramp would look like.

Thanks and hopefully I can make this work. I have 6k pills that are not of much use at the moment.

Does the feed issue look like this or similar?

I would play with OAL a little more.

And I am unsure as to what category that you mentioned that this picture shows.

Is this a photo the result of the cartridge not being caught by the slide quickly enough
OR
Is this a problem with the chambering? OAL related?

My load says a minimum OAL of 1.145\”. I may try that today. Wish the sun were out. 🙂

Thanks for your help. I will get back to you and the forum and perhaps even put this into my review of these
particular bullets.

Learning as I go…..
I got the idea to measure the factory made \”law enforcement\” HP\’s that I bought 10 years ago and they
measure out at an OAL of 1.1.20\” ( Mine are at 1.1.55\” – 1.1.160\” and not feeding)

Using the 2nd edition of Modern Reloading by Richard Lee
They list a min 1.145 OAL for 124 gn jacketed
But then I started to notice that with the same powder
that they list a min 1.050\” for lead and that 5gns is the max suggested load.
124 gn plated has 1.060\” listed as the minimum OAL and 5gn is a midsize load for this bullet.

This extra data has opened my mind to the possibility that I have a great deal of latitude in OAL to try and get this particular pill
to cycle with the G26.

Too tired today and it is raining, but I plan on getting this figured out one way or another in the net few days.
Thanks for all of the input.
If I get it to work I am going to post what worked in the review for this bullet.

The magic is where the cartridge leaves the magazine feedlips as the bullet is making it\’s way up the feedramp. It sounds like you might be too long but be careful of seating depth, it can raise pressure. Not as much with a slower powder like Silhouette but should still be considered. You may need to turn down the powder charge.
