Shooting both .223 Rem & .300 BO uppers on a single lower switching back & forth.



He somehow got a .300 BO round mixed in & extruded it halfway down the barrel of his .223 Aero upper.

At that point he didn't realize what happened. Bolt jammed up couldn't mortar it out.

He brought it to my place & I was able to get the bolt free & low & behold, a .300 BO casing was stuck in the bolt. Popped primer fell out too.



When the rifle jammed up, he said it made a "pop" & like cooked off the propellant with lots of smoke. I had read that same description in another thread here.

I didn't have a rod to try & pound it out so he took it to his LGS & had it removed.

We are all amazed that it didn't kaboom the rifle. The .300 was a subsonic round.

Smith said the barrel & bolt were fine.



He wants to have a jeweler mount it on a chain as a reminder, I told him it would be a better reminder as a butt plug.

Be careful out there.
