Kind of a weird take to compare high end or hand reloaded rounds VS the cheapest of the alternatives.....Pretty sure theres a $100 box of ammo in any calibre - doesnt mean its going to be good.Especially for those who are on a once in a lifetime hunt, use premium rounds, or roll your own.
I would not in any circumstance trust the cheapest 5.56, or 308 rounds for that hunt.
I just got my deer at 180y with a 308 and offhand shot on 7x. Funny enough, with the cheapest ammo as well since it groups sub moa in my ruger.
