Almost at the end of the page, between the .75 Jingal and .950 JDJ, it lists a .750 Hornady. The only dimension is the .765 inch bullet diameter. Does anyone know anything about, have pictures of, or have a round of .750 Hornady?

I’ve never heard of the round. No doubt it’s probably a wildcat cartridge and not an actual Hornady production round (the biggest round that Hornady lists is the .500 NE 3" and .50 BMG).
