Re: 284 win
Get yourself some Nosler 140 grain balistic tips to practice with and some Accubonds to hunt with. These bullets shoot basically the same and will shoot in most guns. With thee bullets I have found seating them into the rifling to work best.
I would recomend H-4831SC and Reloader 17 as being good powders to start out with.
I have used Winchester large rifle primers, CCI BR2, and Wolf large rifle primers all with good success.
