Tried to input data into Strelok pro for my fx wildcat compact with smooth twist x pellet liner and when validating the data, the pellets would shoot high at farther distances. I was using Hardair magazine's BC of .038. I then used Strelok's "trajectory validation" of BC option and Strelok is telling me based on my velocity, my BC is .049. I validated the current BC at different distances by shooting it and it seems ok. Can BC be that waaaaay off from published data?
