The latest barrel explosion ive read was when some moron put 150 grains in a non magnum rifle and a huge 410 great plains bullet and the tip of the barrel ripped open. Yeah the TIP of the barrel, how? Im still wondering why/how the tip would rip before the rear of the barrel.
Just need an obstruction near the muzzle. For example, mud, a second projectile only crowned and not rodded, a ram rod dangling in the bore near the muzzle (though I think that unlikely to go unnoticed). Possibly a single projectile only crowned ( don't think that would cause it either cause I done that accidentally on a few occasions. My sense is that it is unlikelyto split the muzzle without something at the muzzlepreventing a projectile from freely exiting.
