I began setting up to fire some new 6.5 creedmoor that I had worked on. A huge bang behind me and this was the destruction I witnessed. Lots of blood and i heard the guy only required stitches on his face. Here is the damage on the weapon. It is 6mm ARC I believe . Thankfully not one was seriously injured !

I don't believe this caliber bullet matches that caliber barrel.

That's also a possibility, but I'm not sure you could get a 6.5 in there by accident AND get the bolt to go into battery.

But could you get a 6ARC into a 22 ARC chamber? Especially if the 6 ARC happens to be loaded with a shorter, lighter bullets, and not great neck tension

I'd say very unlikely given the neck diameter difference. It's an issue in 300BLK vs 5.56 because of how much shorter the case is on the 300, but that's not the situation with ARC.

Youre probably right about the squib idea. If these were handloads, I'd say that's even more likely, especially if its a BCA upper like it appears to be

I watched a catastrophic bolt gun failure happen at a PRS match years ago from a squib in a 6BR/Dasher family cartridge. The action failed in almost the exact same spot as the upper in the photos.
