ok I will say it.....
you using a .243 good on you.
so you are going to be shooting out to?????300-400 yards...... so what use is chronicgraph information to you???? you arent going to be likely shooting far enough to need to dial up so you arent going to need velocity to last 10fps
if you sight in 3" high at hundy...going to be point and shoot out to somewhere around 250 and spine hold at 300.... its only going to take a couple of rounds to verify your drops...which you will do anyway after using chronograph.
near enough is good enough for ballistic chart to give you your drops give or take an inch.....
but Im a bush hobbit who doesnt shoot past 350 so what would I know...
