New bullet design!
30 cal.120 GRAIN OPEN TIP (HP) MATCH! Fire formed into .223/5.56.
This is what happens when you have 2 AR15 rifles that look the same, but one is 5.56 and the other is 300 Black out, and you mix them up! Blew the mag out of the lower and shell out of the bottom of the mag. The bullet was about 1-1/2" from the muzzle, and I was able to push it out with a cleaning rod. The upper is junk, Bolt broken, bolt carrier splintered, upper receiver split open I don't know about the lower yet. Other than a small cut on my lower lip I am unhurt! It must have pushed the bullet back into the case, because the bolt closed with no problem.
