Run the ballistics, do believe you will find that a 773000 and a 523400 are dead nuts together out to 260 yards. At 300 the 77 has 2.68 inches more drop but 2.1 inches less drift than the 52 so it’s pretty much a wash as you can deal with more drop or with more drift on the 52. Personally with flags out it’s just as easy to deal with windage as it is elevation. So where’s the definite advantage?
I ran the numbers you provided thru JBM and the difference in wind drift at 10mph full value was 4 inches. I'd take 4 inches less wind at 300 every day. Bullet drop on a KD range is a known and constant variable. Wind drift is not. Miss a reversal, pick the wrong indicator and your 52's group is now 8 inches wider than the 77's.
