[QUOTE="Ridge Runner, post: 340472, member: 951"] Niko, I'm not real good explaining things but I'll try, Lets look at it like this, I'm on my favorite crossing, I've glassed a doe feeding in a clearing at 960 yards, I'm shooting my 7mm Allen Mag, running a 160 accubond at 3575 fps with an actual BC of .62, now all my data is loaded into exbal and it'll tell me how many MOA to set for the shot but I'll try to explain it. At 960 yards I am -132.5" from my 300 yard zero, so I take MOA (1.0473) and multiply it by the range in hundreds of yards. 1.0473x9.6= 10.05" so 1 MOA at 960 yards is 10"so divide 132.5 by MOA at 960 yards and you come up with the final elevation adjustment 132.5 divided by 10= 13.25 MOA to make zero at 960 yards I made a shot once at 1350 yards, I was -360.5" from my 300 yard zero 1.0473x13.5= 14.1" or round it off to 14" so 14" is 1 MOA at 1350 yards 360.5 divided by 14" = 25.75 MOA was the final elevation adjustment RR [/QUOTE]
