How do you account for wind in Exbal or other software

The problem is with exbal and not the method.

That's right on. Theoretically I'd say the 1 mph method would be easier to do quickly in your head but, unfortunately, Exbal doesn't cooperate.

I already thought about the 100 mph thing but Exbal limits you to 60 mph. I guess they figure we won't be shooting if the wind gets over 60 mph.

I think I'd personally like to use the 1 mph method for the ease of doing it in my head quickly but I can't stand the inaccuracy of it so it looks like it's 10 mph and some quick math.

.

Do 60 then divide the answer by 60. Then compare that to JBM's with the same inputs. Maybe 60 will be accurate enough?

Anyway... I'm going to give this 1 mph method a try

I compared the results in Exbal using 10 mph and also 60 mph. They were very close, usually within 1/4 moa and 1/2 moa at the most. I don't know how the formulas work that they use and whether the software treats an increase in wind in a linear fashion from 1-60 mph or if there is some difference as the wind gets way higher. I think I'll just stick with the 10 mph factor. It's worked for a long time.

Man, i can't rememver the guy's name right now, but he runs the practical riflery forum--same guy that came up with the Ladder system for reloading. Quite the educated LR shooter actually--Highpower i think. He also uses 1 mph dope instead of 10. I haven't tried it yet with my reticles, but intend to soon. I'm not sure how well it will work with reticles, since i divide the wind by the subtension. It oughtta be easier tho.

SS, hunting here in wv it seems you have 3 different conditions, either no wind, 3-7 mph, or wind gusts from 8-20 mph. real windy days I don't hunt LR much, about 12 mph is my limit, so I set exbal at 3 mph and work from there seems like about evey shot I took last year I dialed in 2 MOA left wind.
