Ouch, I would like to know more about the load used, but God bless these injuries, I have been lucky and only had 1 revolver blow up, I was only the shooter, not the loader or owner of the firearm, wish I had pictures, single action army, cylinder in 3 pieces, and the top strap through the ceiling. The barrel does look thin compared to most muzzle loaders.
Best healing to those involved, looks wicked, and I want them to shoot again.
