Yup, did that with a buddy last week.
On purpose, in front of a high speed camera, using a rest and string…
Would love to see that video
…which is why I choose 7.62×39 and x51 for my 1/3″ rifle rounds. Can’t cross chamber those…
While I like the idea of the 300 blowup, the execution leaves a lot to be desired.
Supersonic will blow it. Subsonic will swage the bullet down to 224 in the barrel.
Supersonic will swage down exit and blow up the gun if the bullet is light enough 110Gr.
[…] When they came up with the 300 Blackout, they wanted it to be compatible with standard AR magazines. Unfortunately, this also means a 5.56 gun can actually chamber a 300. And that will end poorly. […]
So is the AAC case shorter than a 5.56 case? I suppose it’s showing my ignorance, but I had expected the case to be the same for all AR variants, apart from the neck.
Pkoning; longer bullet, shorter case, still fits in AR magazine.
