15 years ago there were civilian 12ga explosive slugs("blockbuster") put out by Power Plus enterprises and also the Blammo Ammo company(made by power plus)......it was a 465 grain shotgun slug with six tail fins, held one cublic inch of flash powder and a #209 shotgun primer in the nose.......I got to play with a whole bunch of them and sold them to local police deprtments.....in broad daylight it had about a 4ft diameter fireball when it went off on target! the slug exploding was just as loud as the shot that launched it. we found it would blow an honest fist size hole in one car door and fill the car with smoke/bust both tempered windows out......a coyote was shot by one and it completly removed a hind quarter(and scattered intestines) in demos we did , a fav was to shoot a .50cal ammo can......one shot would rip off the lid/bend it in a horse shoe shape and fling it 10 feet and flatten the rest of the can(big entry hole) and throw it 10 feet int the other direction. If sombody didnt see the shotgun that projectile came from
they never would have thought shotgun, as its effect was pure military looking, as in grenade launcher. damn those were fun
