I had a squib in my 50cal M3HB. I couldnt hear it so I thought it was a misfife or a round didn't load.
So I started to rack the handle repeatedly with no success. The whole time I was ramming a APIT into the rear
of a stuck bullet and didnt know it. Long story short I eneded up pulling a bullet (in the field) and taping the opening
and firing it to dislodge the projectile. I think it came out sideways...It worked though.

That was a round I loaded
