i've used reloader 15 for 300 savage,250-3000,308.also win 748 for 7mm/o8,not sure what other calibers your loading along with 308 but those powders work good for 308 case size.always heard good things about varget and plan to try it sometime.never hunted elk but if i did i'd want sturdy bullet ,,accubond,barnes,interbond.i'm no reloading pro,,,but i have got lyman,rcbs,hornady,redding dies...and a couple old ch dies.they all work pretty good for me.no low power scope for you?
