Anyone care to clue me in as I don't have a LR scope yet and I'm torn between the Mark IV and the S3. A matched system seems like it would make sense.
Yes you can adjust your power setting on the Mark IV TMR so that the line spacing is in MOA. You need to be very precise however when measuring the distance to the target when adjusting your power setting. Here is the quick math to get you started. I'll assume the target is at 100 yds.
1 MOA = 1.047"
4 MOA = 4.188"
1 Mil (TMR reticle is Mil based) = 3.6"
So set up your target at 100 yds and turn the power ring down so that the 1 Mil line subtends exactly 4.188" instead of 3.6".
Now mark your power ring appropriately. I've done this method on my NF MLR reticle and was using the MOA holdovers out to 550 yds accurately. Just be very precise when measuring the distance so it is exactly 100 yds and your reticle is exactly 4.188".
Or reduce the distance to 50 yds (what I did) and adjust the values accordingly. I'll leave the math up to you.
