Having your firearm explode is no fun, especially when someone gets hurt. A Gunnit member posted about his Marlin lever action rifle chambered in .444 Marlin that went kaboom. While it’s not exactly clear what caused the failure, split barrels like that usually are caused from barrel obstructions. He also posted a picture of the damage to his hand, it looks pretty bad so hopefully he makes a full recovery.
Just warning, the picture below is pretty graphic! You can also see other guns go kaboom here. Stay safe everyone.
