The .284 is one of the world's GREAT cartridges, a brilliant design. It was just way ahead of its' time. If he gave you the dies, it would be worthwhile to purchase a cheap single-stage press and an old powder scale off of e-bay then get a decent loading manual. Thenyou can load the ammo yourself at a lot lower cost. If you don't do a lot of ahooting, you could load a year's supply in just one evening..........
