I am not familiar with those. We drop test and send out to testers to get numbers back. We impact test at range to at or under 2k of velocity. If our BC is wrong then our minimum impact velocity is lower than stated. This was an impact test at 600 yards. First bullet was .600 G1 which is what we are running and used, second is with that .490G1
Either way bullet functioned. BC has been a major pain and we get numbers higher and lower but what we give will easily put you in a spot to true. Anyone is welcome to send in what they get and we will adjust accordingly. We do plan on getting everything verified going forward. Also I am
self taught in all aspects of shooting and the creation of our projectiles. I can and will make mistakes in the process but I am willing to change my opinion when I get new information and always looking to improve.
