I wrapped some tape around a punch so it wouldn't damage the barrel, then dropped it in and gave it a few light taps with a hammer.

The bullet moved down to the end of the barrel.

Next I used an AR15 tool as a fixture to hold just the barrel while allowing the bullet to exit the end of the barrel. The bullet just fell out with a few more taps.

Fix a barrel with a squib load (underpowered charge)
