What Caused This AR-15 To Blow Up? (Video)

I don’t know!

I was using a headspace guage every time I checked a sample. So all I can say is that it was significantly out of the AOL spec for case length.

One of the reputable members over on TOS also confirmed this on some ammo that he had.

I recently checked a sample of some blue box that Mudbug from ARF had in his loading room. It was the same story.

My point is NOT that BH ammo is bad. BH reman ammo obviously has a great reputation. It’s just that apparently .223 can be safely loaded with brass that’s longer than spec.

ah fair enough… if ya get a chance could you measure OAL of a black hills case sometime?

i guess i could just go buy a box of it and see for myself :stuck_out_tongue:

That’s the reason I won’t buy BH blue box. The only reason I buy practice ammo is to get the brass. With BH, the brass is already way beyond my usable specs since I don’t trim cases.

If I run into Mudbug I’ll swipe a few rounds from him for measurements.
