lhonda;
Thank you for sharing the photo with us. It does give one pause for reflection.
There used to be a gun shop in Spokane called The Gunatorium - on Argonne as I recall. Anyway they had a whole row of blown shotgun barrels, perhaps more than 2 dozen as I remember them?
A few of them looked like your friend's barrel with only a small split/bulge and then a few had really "blown up something wonderful" as the Mennonites would say.
Thanks again and all the best to you and yours lhonda.
Regards,
Dwayne
