Great article MD. Just read so late to party. Would like your thoughts on following. If shooting 6.5CM w/142ABLR at 2700 using a ballistic program do I really want to plug-in the Nosler published BC of .719 or some lesser value (down to the G1 of .320) and then start shooting to verify? Thoughts/suggestions? If it helps, 4-16 Viper HS-T w/VMR-1 using Strelok+ program. Mike, NRA life member.
