Herters made some good equipment and a wide variety of things from "Model Perfect" fish hooks to a fiberglass boat (forget the name of it) that had fins that made those of a 58 Chrysler look small, a line of reloading presses, dies, and this Wasp Waist Sonic Missile Tail bullet. Everything they made was "the world's best" and sold with "no hoakum". I bought quite a bit of stuff from them and was mostly satisfied with it. The Wasp Waist Sonic Missile Tail was shaped like a coke bottle with a boat tail base. Because supersonic aircraft had to conform to something called 'area rule' and had a coke bottle shaped constricted area in the middle of the fuselage, Herters grabbed the idea for their bullet, claiming great things for it. It didn't catch on, mainly because it had a short area of bore contact just ahead of the constriction and another short area of bore contact behind the constriction. It also made for an excessively long bullet. I never did use any of them so cannot comment on accuracy.
Eventually Herters went out of business.
