How do you tell the difference between a squib from low powder versus a squib from improper primer ignition?

Well, you to my experience it is not easy if we are talking about pistol cartriges. In rifles, if the load is lower than normal, but still in acceptable range you hit low and if the primer ignites improperly, it can sometimes cause a delayed ignition. If however, the load in bottle necked cases is way too low, even a kaboom/ detonation may some times be the result

squibs from just primers only won't push the projectile as far into the barrel

I had a squib last night, and the bullet barely made it into the lands.  I thought I had a dud I racked the slide back and the casing came out.  The next round wouldn't seat all the way, which I am very happy for.

The inside of the casing is covered in soot like it didn't have a complete ignition.

Any unburnt powder in the action after the squib?

Not really, it look like most of it was in the case.

The gun was a XDm 45, with a 230gr HAP bullet over 3.8gr of Clays w/ Winchester LP primer.

That is a classic squib caused by a primer only round with no powder.

Worked fine for me



Really sooty case, I've had one squib, but it was like 30 years ago and the only thing I remember was the bullet stuck in the barrel.

Usually its been my experience. Cartridges without powder stick an inch or so into barrel. Half a grain or so will stick one just before the muzzle and a grain or better will send lead bouncing across range floor causing all shooters to stop and stare.

Like to say no experience with squibs, sad to say in my early years loading progressive I found that "one" resulting in humped Barsto barrel. My take on squibs. No excuse for one, ever. Murphy screws with the best of us and I'm honest enough to say I had a first in years loading on manual index machine. Eyeballing is ultimate powder cop.

I’ve seen a number of primer only rounds from friends who shoot IDPA with me.  The reason for the really sooty cases I think is because none of the ignited material can escape the chamber area and so is all deposited on the case surface the back of the round.

So there was unburnt powder in the case?
