AR-15 Kaboom Hot Load

He's one of us!!


Did you guys see the Ultimate Bullet Button Tool in the bottom of the PMag?

All right CalGunners.... Who was it???

Would be nice to hear some more details on the load though.

Pistol powder maybe, is it hard to double charge .223?

[Exodus343]

need load data to see the problem

Wonder what material that bolt carrier was.

Crap!

[ZRen]

My guess is pistol powder

[Munny$hot]

Wow, very scary! Are there any signs to watch for that lead to case head separation?

Inspect every round for cracks, bulges, and sharply creased dents especially around the case head and neck. I case gauge and inspect every round, you''d be surprised at what you will find. Backwards/sideways/high primers is the most common.

My guess is pistol powder

Probably not unless it was the first round since every round after would have fast burning pistol powder too.

Lesson learned:
1. Inspect your brass
2. Shoot your own reloads
3. If you shoot someone elses reloads, commercial or not, make sure it's reputable company

I bet it was a high primer.

I bet it was a high primer.

Im not familiar with the term "high primer" please elaborate ...

Guys that took ALOT of power. Ive seen people test 223 ammo in AR's that was HOT. They must have used pistol powder. Ive never seen an AR blow up like that before. I seen a ****ed up gun from hot loads (mixed power, pistol and rifle).

I'm no AR expert by any means but why isn't the bolt lugs sheared or even marred? If it was a case failure it would of done damage to the barrel shroud or the bolt lugs wouldn't it? Also it is damn hard to disengage the bolt via bolt first carrier group second. Also with the bolt jammed so far back into the carrier, the bolt face doesn't have much damage to it.
Looks to be a headspace issue or out of battery issue coupled to a hot/incorrect reload. Just too many unanswered variables.

This is disturbing... been thinking about this since I saw this . It appears the bolt came back with such force it split the carrier. . The bolt had to rotate before it can come back yes ? Just thinking out laud here..look at the gas key..soot at the tip.. so the bullet had to pass the gas port for the gas to reach the gas tube and key..then rotate the bolt and force it back hard enough to split the carrier. Seems to me the case head failure is a symptom and not the cause. Pistol powder or a mixture makes sense. My sons and myself all shoot my reloads..so again...disturbing.

Russian guys comments are hilarious!

I'm glad I wasn't the only one that laughed at that guy

This looks like a case full of a fast pistol powder in a rifle. I doubt you could get this level of carnage with an over charge of the proper rifle powder.

high primer = primer above the base of the case, bolt face touches off cartridge before lock up.
