Rifle he popped a yote with the other day, Daniel Defense .308, I put a different scope on to play at distance. It's in mils, working up a dope chart yesterday. Zeroed at 100, backed off to 400. Factory Norma 147 fmj put two 400 yd shots at slightly less than an inch. Middle of afternoon, heat mirage got bad so we stopped. Chronograph is key and mine had dead batteries so we were winging it on fps, just using the info off the box. Need slight adjustment left and up to be on.
