My experience is it is impossible to double charge a 223. You may get a tiny bit more in but like you said , using proper rifle powder, it won’t happen.

Is it possible the round before this one had a light charge and was in the barrel when this round went off? I'm trying to figure out what this, where the "1" is at, is on the back of the case? From the other pic it's not deformed on the inside and wonder if this is what led to the failure? You can see this is where the primer rotated outward to release the gases and may have caused the blowout.

I ran about 500 rds of their 9mm without issue. Also about 300 rds of the 223 but not reloads. No issues with any of them except 1 223 didn't detonate on primer strike.
Wow, that’s a lot of recalled ammo!
As pictured in OP - this was 69 grain. Not addressed in any of those recalls.
For folks asking - there was no squib in the barrel. No modifications other than cosmetic. Barrel was clear other than the brass case from the failed round, which blew off cleanly at exactly where the bolt and breech face meet. It was still in lockup on disassembly, if it wasn’t - there would’ve been more severe injuries.
I hate to pop your bubble and I don't mean to offend you but in my 47 years of reloading, I've learned that you can. I own a pretty good library of reloading manuals and the first one I grabbed was the Speer #9 (1974) and it showed charge weights from 8 grains to 29.5 grains showing that it's possible to even triple charge a round. Bear in mind that people that sell reloads do it for profit and they're apt to use powders with a low charge density to get the most rounds per pound. It's easily possible to double charge a round.

Iv run a few different offerings from them and I like their stuff. (pro tip - fill the cart and then leave the page for a few days. They sometimes send a 5% off coupon that gets my shipping close to 0)
That particular table is IMR SR4759 which is out of production but the Speer #14 (which is more current) shows a load of 11.0 gr of AA5744 which is still available. If I dug deeper, I'm sure that I could find more. The point is that a .223 could be double charged.
OK you got me...but you had to use uncommon, obscure powders to do it. Like you stated they are in it for a profit and at $74 a #, commercial loaders probably aren't using it. They are probably using less obscure ball type powders which could make it harder to double and I'm not sure the triple charge with that powder would fit either.

Depending on the bullet grain you can use up to 21.1 gr of 5744 for a 35gr bullet. The lowest load data I can find is 16.8 gr.
The Speer Data you are looking at is for a Reduced Load. Not sure why they are only showing the reduced load.

See my response to his post. I agree with you on the obscure powder. 5744 is a very fast powder for a 223 and only used for light rounds to 55 gr. I had to do some digging as he only used Speer #14 book and didn't look at Hogdon. The 11 gr is a reduced load for under 2000 FPS. The full charge data is double that and in line with many other powders give or take some grains.
Update: the ammo manufacturer has concurred that this was an ammo malfunction, and have agreed to make me and my friend whole. I have edited their name out of the original post.
Moving forward, time to build a new rifle!

It's plastered everywhere.
You mention no one was seriously hurt and Freedom Munitions is making and your friend whole. Hope you both recover 100% from your injuries.

IT seemed that had to be the case based on the base zoom in I posted. It didn't look right at all. Enjoy the new build.
