-punch in your data and print it.
THEN go out and shoot at 25yd incrments and adjust accordingly then you'll have YOUR settings.
I used this recently w/a 22-250 and it was dead on out to 450yds ->got lucky.
My 25-06 was barely on paper.
I'm back and forth on the mpbr= max point blank range -i don't like the bullet going above a couple of inchs midway in the trajectory.
Enjoy the software ----------Mike
