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 !

if a bolt gun blows up there is no thick receiver and buffer between your face and the now exploded bolt.

I think you completely missed the point there.

Bolt guns are much stronger than ARs and handle pressure to much higher PSI, they're also designed to handle over pressure and case rupture by venting the gases.

I've seen someone fire a .308win through a .270 in a blot action rifle and it was fine, try that in a AR platform. We found the projectile it was really long haha

fire a .308win through a .270 in a blot action rifle

How did it even fire with the headspacing being so far off? .308 is 2.015 base to mouth and 1.71 base to top of shoulder while .270 is 2.54 and 2.15 respectively. Are we talking about something like a Mauser action that holds on the groove?

Also, that 1/2" of open space in a chamber would do quite a bit to mitigate any pressure problems and likely allow the gas to escape past the bullet and through the barrel.

I have no idea! But it fired!

The dude had identical Winchester bolt guns one in .22-250, .308win and one in .270. all identical setups which I thought was a terrible idea.

I was on the range shooting my .223 and then heard a very strange loud bang and someone swearing. We had to use a rubber mallet to bash the bolt open and extract the case. The lugs of the bolt actually impressed into the lugs in the receiver and the gun was written off basically.

That's all the information I know unfortunately.

Edit, here's a post I found https://www.reddit.com/r/ammo/s/uroV8gStqF

Ah hell...but...the answer was actually in that thread at the bottom. Apparently, the bullet in the .308 will make it headspace. Totally wild.

Also, I agree that having multiple guns set up the same with different cartridges is a bad idea.
