The big Interbonds first announced Hornady rounded up the standard industry word salesmen and took them on a cape buffalo hunt that was supposed to be a promotional field test, and press release for their new bullets and factory ammo useing them. There was also a new line of solids with the same gilding metal jackets.
The paid for story was published with writers half-heartedly pointing at some dead buffalo, but the specs on the shattered, broken and turned inside out bullets left a bigger impression. The term "damning with faint praise" seemed to fit. Things never got any better after that. The solids didn't fare any better. The lessons learned 100 years ago about solid construction seemed to be forgotten, and testing must have been non-existent. The "old pattern solid" was suddenly a valued commodity and was brought back into production. Hornady's mistakes were quietly dumped.
The DGX that came next isn't a buffalo bullet either. I've personally used it in .450 Nitro Express and about the only good thing I can say about them is that that's what the VC was regulated with.Won't be useing them again.
