It all comes down to knowing your ML. What was it sighted in for? My ML is sighted dead on at 100yds, but I shoot 120 grains of powder with a 250 grain bullet, so very little drop under 100yds. A lot depends on the bullet, some guys shoot heavy bullets and 100 grains of powder and they have a lot of drop. It helps to have a buddy rangefindin for you too. I'm bad at yardage sometimes I say its 100yds the laser says its 140. That can make or break it.
