Has anyone else on here compared these two ballistics programs side-by-side? If so, do you find JBM to be more accurate?
For me JBM seems to give me almost dead nuts drop data whereas Shooter takes a lot of tinkering with velocity calibration to get it to work. Both programs I have used the Litz BC and all of the same inputs (I triple checked the inputs to make sure I didn't do anything different). The only difference is Shooter asks for bullet length and JBM does not.
For example, today I was testing a new load with 139gr .264 Lapua Scenar bullets in my .260 at 600 yards. Shooter gave me a correction of 3.1 mils, actual adjustment to get correct elevation was 4.3 mils but that was ever so slightly high but due to time constraints I could not correct and re-shoot. It was bothering me on my drive home why Shooter was so off so I decided to plug all the same variables into JBM once I got home. JBM gave me a correction of 4.1 mils, which is probably perfect since 4.3 was slightly high. This is the 2nd time this has happened to me.
Curious as to what others' experience is between these two programs.
