Hi, this is a documentation of my project revolving around the 12 guage shotgun shell and my aspirations to build a slug that will reach out to intermediate rifle ranges (preferably 300 yards), have large amounts of impact shock at those ranges, while still also being capable of creating good tissue damage. To do this i have created a self stabilizing slug shape unintentionally based off the Minié Ball out of a CO2 cartridge that i used as a mold, i have made this "body" out of aluminum and have designed a steel weight/penetrator with similar proportions to a 5.56 M193 ( a little bit smaller so that itll fit in the shell). My goal is to have the aluminum body impact the target, transferring a large amount of energy to the target via direct energy transfer, and then for the steel tip to come apart from the rest of the slug and tumble inside the target. I have already made lead versions of these slugs without the steel weight and at roughly 100 yards they had great stability so im very hopeful for this shape. I have not yet shot the aluminum ones, primarily because i only have one as of right now and am awaiting a crucible to cast more. I also plan on sending these to the youtube channel Taofledermaus so that they can test them at longer ranges and against ballistics gel with their high speed camera. Questions welcome as long as they arent retarded.
