What a bunch of nonsense. I read through the patent and their marketing stuff surrounding this. It’s hardly a new “technology”, or even a technology at all. It’s just a ratio that works best for their bullet design. A rule of thumb at best. People have been studying this stuff and applying these techniques since at least the 40’s for supersonic objects. Schlieren photography has been around even longer. Most artillery shells have a flat tip like this too, hardly new. I’m not sure what’s more surprising here: Hornady revealing it took them until 2018 to use known techniques I would’ve assumed to be standard stuff for a ballistician, or the fact they were able to patent something which is so clearly not novel. I’m hardly a Hornady fanboy or hater really but I get why people can’t stand these guys sometimes.
