MOA Adjustment

[Clem Bronkoski]

This doesn't sound right to me. I'm limited to my long range shooting areas and my current range only goes to 300 yds. I've shot at 100, 200 and 300 yds and confirmed my zero and MOA correction. Now I was playing with the Hornady Ballistic Calculator and my correction and the calculator's results were spot on at 300 yds (4.7 MOA). What doesn't sound right is that when I introduce a 10 MPH 90* wind my MOA correction drops to 3.9! This correction changes as the angle of the wind changes. Should I be using that wind correction or just go my my actual results with zero wind?

Areodyjump cross winds yes

On Ballistics AE my dope for 400 yards is 4.9. On Hornandys app it's 5.7. Can't figure that one out.
I verified my 400 yard dope and it's dead on at 5.

Your calculating and truing down to tenths of MOA?

Yes, that sounds right. You must have also input that your rifle has a right hand twist. Try putting the 10 mph wind in from the opposite direction (270 degrees). The elevation correction will go the opposite direction - probably over 5 MOA in your case. You can find charts and explanations for this effect - one example below.

When will it be available for Android?

Still waiting for the conversion gentleman to finish apparently android has a hard time with ballistic apps that do this much

I gave up on 4DOF. AB and even the non 4DOF version of Hornady app brings my bullets to home just great.

I need to look at that Eagle app.
