Call me crazy, but I think Hornady has missed the mark.
They produce a lovely 32gr V Max ... perfect for legitimising a 20AckleyHornet. They'd have the market sewn up for projectiles, brass, ammunition and dies in one hit. Release a lighter 20cal pill and they could create a niche for a shorter ranged 20cal with no competitor cartridge to worry about.
Those that shoot Calhoon's 19 Calhoon rave about the little 19cal.
Cheers...
