The 284 is one of those magic cartridges. Big reason I’m always saying there’s nothing new. It was designed like a target cartridge of today in the early ‘60’s! With less body taper & a 35 degree shoulder. (Hornady didn’t invent a darn thing with the Creedmoor.) Only problem with it is it’s useless to those who don’t reload. Factory ammunition is nonexistent! But for a normal reloader like myself, and especially a Wildcat’r like Fuj’, it’s a winner.
