220 Partition, bllet drop/flight question

[dkmlever]

I am going to use a 220 gr Partition in my 300 Weatherby, 70.5gr of IMR4350 going +/-2770 fps. Can anyone give me the flight trajectory, where I should be at 100, to be dead on at 200 and what the drop would be to 300 and 400 yards? Thanks.

Slap turrets on the scope and you will be golden until you run outta moa. Looks like 11 moa for 500, 8.5ish for 450, etc etc.
