Jim, the math doesn't lie its the reason it is used. Now I would like to know exactly how are you testing to determine B.C. what data are you gathering and how are you figuring it.....theres more to this than just drop, the drop is just the end result....
No math does lie but people do, like Bergers BC with the old Hybrid. and the BC. given for it at 1.270 long and they were no where near it. OK the 110 SMK BC.600+ @ 2900 Verses a 105 BC what ever @ 3000 SMK shot 2minutes flatter that the 105 from my 100 yd. zero to a 1000. I think that is a true evaluation of BC . Most adjust their findings to fit their point or need or sales pitch, only true evaluation is send them for a ride and see for your self. Kind of like trimming and pointing..... jim
