This is a Federal .22lr bought at Walmart (one of their bricks of about 500 rounds). It was shot from a fairly new Browning Buckmark Hunter.
No problems with any other rounds, either before or after this one.
When I fired this round, a plume of smoke came out of the breach and my right hand was covered in metal shards.
I'm not sure if the casing was defective or if the bullet wasn't properly seated. If the former, nothing for me to do (other than avoid the brand/source). But I wonder if the round wasn't sitting properly.
Can anyone deduce what happened given the image?
