When I was a kid my dad had a small version of a 155mm Long Tom that shot carbide. Man that thin was LOUD! Then when I was a teen we’d buy carbide at the hardware store and spit in a can with a piece of carbide in it and hold a match to it under our feet and blow the lid off! Surprised I’m even alive after some of the stupid stuff we did!!!The "4th of July " cannon I made , and aluminum non-shooter for my dadView attachment 258436View attachment 258437View attachment 258438
