Sks squib ?

Maybe there was a “click” and the slide Partially opened and I mistook that for a jam so racked the slide and ejected the case and the new round went to chamber and luckily it wasn’t able to. That’s the only thing I can think of. Is there any other reason a squib load can happen aside from a light powder charge?

Projectile 1 inch down the barrel is indicative of a squib caused by insufficient powder, primer only.

As for tips using frangible projectiles: Don't crimp, it can crack the projectile. You confirmed a dummy round drops in and out of the chamber easily? Using the proper expander ball in the sizing die (.308 or .311) for the projectile?

There's no way a split projectile stuck 1" down the barrel would cycle the action. The gas has to make it from the gas port up at the front of the hand guard to push the piston back. He probably thought there was a misfire and tried to cycle the gun when in fact the bullet was pushed out of the chamber and got stuck in the barrel.

If you ever have anything less than a full power recoiling shot or a "misfire" and a complete cartridge with the bullet does not come out, STOP EVERYTHING and check for barrel obstructions.

It was really fortunate for you and your friend that the bullet was not lodged a little deeper into the barrel. A kaboom like that usually only results in a lost gun, stinging hands and maybe some particles to the face and arms but you need to teach others what to do when shooting with you.

This is another case of someone shooting someone else's reloads. Technically, it is all your stuff, but you are still responsible for the safety of others.

I don't think the jammed bullet (incident #2) is due to the frangible, you said a complete bullet came out. That implies no powder unless there was a bunch of unburned powder that spilled out when he cycled the action.

Your incident #1 was probably due to the frangible. Follow smoothy's advice or better yet, don't use them in that gun or at least don't let anyone else shoot 'em until you can prove to yourself that you can shoot a couple dozen without incident.

Fantastic words of wisdom. I never knew a squib could go off with out a pop or sound, but after this experience and more research, I now know and am very lucky.

Pull all 60 remaining rounds. It's a pain, but be safe and do it. You can reuse the components of course, but might was well do it and check to see if there is another squib in there.

[Brbecker]

Yes I think that’s great advice. I just ordered a bullet puller collect for that caliber.

You said you had a Dillon powder measure, didn't say a Dillon press. Something to think about with any progressive, if you have a round with no powder, you may have a round with a double charge. Not at all likely, but powder can bridge, then get knocked loose on the next drop. There are other unlikely scenarios, but you can't be too careful.

[Brbecker]

Yes using a Dillon powder check, the one that beeps if the charge is off. I have a feeling that something got switched because I was having proble with the stick powder in my measure. It’s been decided that I will only use ball or flake powder in this Hornady lnl

Another nice thing about rifle rounds is that you can usually feel the powder charge in each loaded cartridge. Unlike pistol rounds, there is usually enough powder that you can feel the powder bounce up and down if you shake the cartridge vertically. Most standard rifle rounds are loaded 80-95% full and you can definitely feel the difference between a good charge and an empty case when you shake it.

Overcharges
A double charge will spill powder everywhere and most rifle powders are "OK" to accidentally fill to the base of the neck without blowing up a rifle.

Very little extra time wasted and worth its weight in gold if you catch a boo boo.

I really think you had a no-charge that slipped by rather than an under charge but regardless, no harm done and you learned from the experience.
