I am in the process of working up some 7MM RM Mag Loads (160GR AB, 66GR RL25, +/- 2931fps) that I intend to use this year for elk. I have a low profile 10x Leupold VX3 mounted atop a Browning x Bolt 7mm. I have and have figured out the overall length that gives me the tightest group at 100yds (sub MOA) and finally took the gun to the 200 and 300 yard range last night. I have the scope right on at 100yards, at 200 yards it was shooting about 4 inches low and at 300 yards it was shooting about 14inches low......for final adjustments I have always set my scopes to shoot about 2.5in high at 100 yards but would like some input from those smarter than I...I would like to be able to maximize the range the load is capable of....should I be at 2.5in, 3in high....to get out to 300 yards and hold dead on?
