What do you get when you know a professional machinist and he just so happens to have a chunk of aluminum at his disposal? If you’re YouTube personality TAOFLEDERMAUS, you get these large, rifled aluminum slugs. In addition to other things, TAOFLEDERMAUS is known for pushing shotguns to their limits by shooting shells loaded with an assortment of weird objects. To absolutely nobody’s surprise, most of these score pretty horribly in the accuracy department, and viewers have often said that it’s because of a lack of rifling. Well, this time rifling is not going to be a problem—but how well will these .70-caliber slugs perform?
