Problems at the range

[Marauder2003]

Went indoor shooting with a friend. He was using a Glock with his own 9mm reloads. He had many failed fires. The firing pin strike looked good on the primer. I took some of his duds and tried them in my FN 503. About 50% failed to fire. Some of the primers were a little proud of the pocket.

His other problem was 2 times after a failed fire he could not rack the slide to clear the bad round. Trigger was back in the pulled position. One of the range masters managed to loosen the slide up by firmly hold the slide and very sharply striking the grip in a forward motion. Not sure what was happening there.

I have no info on the brand of primers, powder or reloading machine.

Never, ever shoot someone else's reloads in your gun.
Your buddy needs to read a reloading manual because he's doing multiple things wrong.

I had an issue with .223 rifle loads, that sounds similar to your friend.
You wrote that some primers were proud of the case.
It's possible that the anvil in the primer didn't function because it wasn't touching the web of the case.
That was my situation anyway.

This ^^^^^

it sounds like the rounds arent crimped in the final step or the COAL is too long (and getting jammed in the throat)

not crimped right not sized right not primed right not plunk tested on and on lousey reloads should get some pointers

Buy new ammo. 9mm is under 300 per case.

Short stroked the primer seat. 1st strike seats the primer, second goes off.

Crappy reloads give you crappy results. With several things wrong, you friend needs to stop and show someone who knows what they are doing teach him. Primers not seated fully will fail to fire. They are often so boogered up after the first strike that seats them, they often won't fire a second time. Getting stuck means he is not resizing them properly, not checking his brass after loading, not removing the flare enough, and not checking chamber fit after loading one or two.

Buy your friend a case gauge.

He needs to go back to the beginning phase of reloading. Read the reloading book carefully. Remove all components of the rounds that he already put together. Re-start all over. The positive thing is none of his rounds blew up the gun in his or your face.

My guesses:

1) primers not fully seated. Firing pin strike put its energy into seating primers deeper rather than compressing the pellet between the anvil and cup. Further evidenced by the proud primers.

2) Insufficient crimp (case mouth dragging on chamber wall), insufficient seating depth (bullet jammed into rifling), or bulged case from either not enough flare before seating or trying to apply too much crimp (bulge causes drag as the cartridge enters the chamber; slide has enough inertia to force it in, but you don't have enough leverage to pull it back out without firing it.)

The "hammer the grip" method works in some situations if you can hold the slide firmly enough. As does placing the dust cover against something solid and hammering the grip. Successful plunk test prior to shooting will avoid this one.

These are guesses, but you should be able to tell what it is with a little testing.

Good advise so far from others, and here's my 2?.

When the cartridge is jamming up the action and you can't rack the slide to eject it, that is caused by one of two things. Either the projectile is contacting the rifling, or the case mouth isn't crimped enough to completely remove the belling/flair.

To correct the first is obvious. Simply seat the projectile deeper by 5 or 10 thou making sure to adjust the powder charge accordingly as to prevent overpressure.

The latter requires a correct setup of the crimp die. Most reloaders don't bother to trim pistol brass which is fine as long as you use a short case to adjust your crimp die. This will ensure all will have sufficient crimp to remove the flair.

Also, bullet seating and crimping should be done in separate steps to help with consistency.

Primer not seat fully and brass not sized correctly or it has the glock smile if it range pickup brass. or seating depth is to long

[Old Flash]

For sure, a lot of good advice posted here.
My 2 cents is to do "plunk test" which I've read on this forum a couple times for testing reloaded ammo.

As already stated, seems like the basics of reloading have not been applied.
