If this KB is truly the fault of the ammo, then I feel bad for HSM - they seem like a good outfit. They have been doing a lot of group buys across the Internet and perhaps this indicates a slip in QC, (too big too fast). I have used their 7.62x51 and found it to be excellent, but this shooter clearly had a bad day…
The author of that thread evidently doesn’t know that you can’t “double charge” a rifle load. I’m assuming he means an over charge of propellant.
It’s funny you picked up on that, as I just reread the thread and came back to pose that question. Not being a reloader, I still got a puzzled look and said to myself: “double charge??”
Yeah. A pistol charge like .45 acp can easily be doubled. I almost did it once. 
But with rifle, the correct charge fills nearly the whole case. I’ve gotten to where I visually check every powder charge I load before I put a bullet on top of it.
thats right espeically on the 5.56 cartridge ! there is no way you can double charge it since your 1st charge is already almost 3/4 fill or more dedpending on the type of powder and bullet selection.
maybe a old weak, fatique brass that cause that!

I didn’t read the linked thread, but presumably this means the rumored Glock Carbine has hit the market?
I wouldn’t think so. Typically the case will separate or the neck will split. I’ve had it happen a few times, and it didn’t cause any signs of over pressure.

lol :eek:
HSM is having some major problems. they lost a big chunk of their staff when Darren went off to form his own company including the good people. HSM also had a bad batch of ammo go out that should have been recalled but wasnt. I dont see them being along for long if some things dont change really quick.
Looks like case failure.
Crap took care of that carrier pretty good
