    Click.... Boom. Casing stuck in chamber, magazine blown out, extractor broken.

    The ammo manufacturer looks like they'll cover it, but need a gunsmith with experience in .50 cal.

    Wow, hope you didn’t get hurt, and we’d love to see pics!
    There’s a machinist in Ral area that has made them, I’ll see if I can get up with him.

    I'll get some pictures together- I need it to send to the ammo manufacturer. I was lucky I wasn't hurt- and honestly that more damage wasn't done. The worst thing I got was a face-full of debris- that probably was unburnt powder which was all over the 'lower' (the BA50 is an AR-ish design).

    Give Josh at Patriot Shooting Sports a call, he's familiar with stuff up to 20mm.

    Was it the ammo, or Bushmaster/Remington/Freedom Group?

    Consider sending to manufacturer.

    Pics would be awesome! Severe over gas....have you fired the rifle previously? Wondering about head spacing and such. It would be great to see where the firing sequence failed and left evidence. Is there a ring above the extractor groove on the case? Soooo many questions....glad you werent hurt!

    Yes, I've fired the rifle 20-ish times. Headspace is a theory as well, but seems less likely than a bad round. I hope the gunsmith can determine. I did write bushmaster and they said to to ammo manufacturer first.

    I've got an email into Patriot- thanks.

    Looks like the magazine acted like a "blow off" valve and vented. The case head looks skewed too but maybe just the pic angle. Have you tried tapping a wooden dowel down the barrel to see if that case will push out? Maybe hit it with a blow dryer beforehand to change tolerances and loosen it up.

    Yep, I didn't notice how much the magazine was damaged until I saw it side by side. Since the case looks intact all the blowby must have come through the primer hole. There was unburnt powder in the lower. I'm taking it by Patriot today.
