Take the most accurate. I likely don't need to add "know the trajectory and take a rangefinder".
Often not necessary, but....
I took "my" first 3 rams at 20 yds, 50 yds, and (wife's), 70 yds, respectively. Hers was biggest. 3 successive years, all within a half mile of each other.
When you find something that works, why change it?
Looking forward to some pics and a yarn.
