Reloading 9mm and got some squib load need help

[tabascoz28]

Assuming those were clean brass before fired, that looks like low powder or bad powder? Bullet never escaped so all gases were inside the gun?

i bought a hi-point just to get rid of some iffy gunshow reloads safely

They look like they are under charged. What was your recipe?

The oal is too long , the bullet is getting stuck on the lands of the rifling. My cz's have the same issue when i started reloading. A little trick i learned was to dremel an empty case down the side to make a relief cut , seat the bullet just so it can hold it in place . Then push the round into the chamber and that will tell you your max oal . If you don't understand my crappy english then just google the split case method OAL for a better explanation.

Plunk test?

Not sure

I was pretty sold on the "OAL/hitting the lands" answer until the photos. How could he have powder spilling out of the chamber AND the black soot on the spent brass?

The part I don't under stand is that when shoot threw my glock 17 not one issue why is that

The shiny ring around the bullet crimp suggest a strong crimp, through the coating to the lead (shiny).

I think it’s a squib with no charge, with the primer barely enough to fire the bullet with the strong crimp, that’s why we see no rifling marks on the bullet. The soot around the case may be from just the primer, I am not sure if it will do that but if these were the correct cases then there was certainly some ignition.

Edit - nevermind, saw the unburnt powder posted originally. It’s strange. The bullets show no sign of grabbing the rifling at all. I’ve personally loaded one squib, it was a mouse fart uspsa load with 128 power factor and it went halfway down a Glock 34 barrel. For a bullet to be still pretty much in the chamber, the logical explanation is too long coal. The round feed but didn’t chamber due to too long coal, the barrel throat grabbed the bullet because a pcc chambering is pretty strong with a direct blow back bolt, you pulled the trigger and it still clicked because the previous round had reset the trigger, and when there was no bang you extracted just the case spilling unburnt powder. Are you sure you have the right cases? Do you have cases with intact primer? In my scenario the firing pin wouldn’t have struck the primer.

Cases comment...

Exactly, we have a great theory which explains everything (including why the rounds work fine in his Glock). But only if OP's mistaken about which cases were on the squibs.

I'm having difficulty understanding how you can have a fired primer and unburned powder. It doesn't make sense.

Bad powder or bad (partial/slow ignition) primer will do it. Contaminated, old, whatever. Not real common, but certainly possible.

Is that a Ruger takedown PCC? They are known to load short. Rounds loaded long for a glock may be too short for a Ruger PCC.

1). Take say 20 rounds from the batch and measure OAL. Check for variance, see if some are much longer than others. If some are longer than others, then you have inconsistent seating depth.
2). Take the longest rounds from that test batch and plunk test in the barrel. If it doesn’t plunk, or if it doesn’t chamber correctly, then I think you have your answer.

That depends on if it was intermittent or if it happened every time. The laws of randomness sometimes makes things look like cause and effect.
