ZekeShikarI'm headed to a family Christmas Eve party and then headed coyote hunting Christmas afternoon, for the weekend.
If I catch a few minutes, before Monday, I'll do it for you or I'll do it Monday....unless someone drops the info for you sooner.
I can get it close enough with the info you supplied, at those ranges, but if you want to include sight height above bore (center to center) and chronographed velocities, that would be a bit more accurate. I can look up the bullet's BC.

john c.i will look up sight height if/when i get a chance. but otherwise approx is fine. thanks

Lamarunless your shooting ground squirrels just raise the clicks up about 2"s then point the cross hairs where you want the bullet to go.
nothing bigger than a rabbit is gonna know the difference.

john c.hmmm...i double checked and STILL can't see where i mentioned i was gonna be shooting critters in my request. maybe i typed it in invisible ink?

ZekeShikarJohn,
I had to assume many things and the biggest was the actual velocity you’re getting with those 3 loads.
Here’s what I came up with.
At 2650 fps your drop at 200 would be 3.72”
At 300 it would be 14”
2700 fps
200 yards 3.56”
300 yards 13.41”
2750 fps
200 yards 3.36”
300 yards 12.75”
I suspect these are relatively close numbers assuming sighted in at 125 yards, 10 twist barrel, .462 bullet BC, 1.5” scope (sight height) and the velocity of your rifle.
Merry Christmas,
Zeke

LamarI double checked and seen nothing stating you weren't.
most target shooter would just shoot targets and count clicks and move on.
