Thread: Mac ballistic software

Thanks Stug.
I used the JBM online for the 308 I wanted to make a drop chart for.
Checked it on my 400m firing range. Dialed in 6.25 moa ( 0.25 increments on the Nightforce ) as chart showed 6.3moa and the point of aim was only 50mm low to the center of the group shot.
I guess thats about the same as the 0.05 difference between the two.

So updated the drop charts on my 300 and 6.5-284 and will test them when able.
