I wanted to post a thread for those of you that have trained here at CVT and for the ones that can't make it. This will be a review of wind reading basics. First thing is our formula: Inches X wind speed / by 1 minute of our distance. We have to have a range card that breaks our wind down to 1 mph. So that it shows us how many inches our bullet will move for every 1 mph of wind speed. Here's link to a ballistic chart you can use. You can fill in the blanks but be sure to only use 1 mph of wind speed rather than 10 mph.http://www.eskimo.com/~jbm/calculations/tr.../traj_card.html
Now it should look something like this:
Now the one on the left is for 40 degrees and under. The one on right is any over 70 degrees. Remember these are just a starting place. Now notice the column that reads 1 mph wind. Now scroll down to 600 yards. Both cards say at 600 yards your bullet will move 3" (inches) for every 1 mph of wind speed. So if we have a wind speed of 5 mph all we do is multiply 3" x 5 mph= 15" So now we know our bullet will move 15 inches in a 5 mile per hour wind at 600 yards. Now we need to change this...
