No, not a kaboom this time thankfully. I attribute that to the shorter bull barrel of my .300blk AR pistol, and the fact that the cartridge is spec'd at a much lower pressure than the 5.56 bolt and AR type action is capable of handling. Also I am glad I had a H2 buffer to tame some of the recoil of the very overpressured round. I also was loaded the rounds to a OAL of longer than spec (since there's room in the mag up to 2.300 or so
The gist of it is this:
I mixed up the projectile boxes and though I was loading 125gr Nosler BTs. I did it late at night (mistake #1), I didn't read the box and assumed because it had a nice little green tip (for .308 cal) that it was correct.
The next morning I went hunting, took a shot on a little 3 point cull buck at close range, and lost the deer.
So as I was going thru everything, I took the gun over to the steel plates and the rounds were louder than usual, had way more recoil than I recall, and the brass started sticking and causing extraction issues.
I didnt immediate inspect the brass but when i did I found the blown primers.
I was loading 168gr pills at 17.5gr of H110. The max for that weight bullet per the Hornady manual is around 15.
Primers blew out of the shorter COAL rounds I had loaded, and I had ejector and extractor swipes on the case.
When i disassembled the BCG i found a primer had lodged itself in the piston area.
Lessons were learned. Glad it wasn't the hard(er) way.
