I just read Bryan Litz's "What's Wrong With 30 Caliber" article, and noticed that with heavy bullets/VLDs he said that they more closely matched the G7 form factor. How do I figure out which form factor I need to use when running trajectories through "JBM Calculations." I used G1 & G7 on the JBM page, and got dramatic differences. Any help out there.
Thanks,
Shane
