I was working up a drop chart for a 22-250
Here is the Data
MV 3695
Zero is 100 yds
Sight Height 1.8
52 Grain Custom Bullet
.225 bc at a G1 (Educated guess)
Temp was 80.6
Pressure was 29.92
Angle 2.1 degrees
Altitude 210 feet
I was shooting at 600 yards. Came up 90 clicks (1/8) MOA to give 70 and change inches of up. The shot was 10 inches low but in a nice little group on my steel. Adjusted my bc value to .200 and it now shows a drop of 80.6 inches given the same variables. I was not able to verify as I ran out of time. Is this what you would have done in this situation?
I figured my speed was a given , BC was the only thing not certain. I am sure I could repeat and verify but I want to be REALLY close and take out the "Experiment" if you know what I mean.
I have heard of guys adjusting speed and not BC to get their charts to line up? What do you do? I was taught to adjust BC.
