[QUOTE="FURMAN, post: 1540796, member: 26535"] First I personally feel too many people worrying about most things too much inside 4-500 yards but to address your statement I do not know of anyone personally who chooses higher bc for trajectory. I know there are probably thousands that do and I did when I first got into shooting long range. The thing that bc really gives you is more room for error on our wind reading. We have rangefinders to tell us distance. I am assuming good shooting skills and proper load holding vertical is not a problem. The biggest problem in long range shooting, wether it be competition or hunting, is and always will be wind reading. BC rules in the wind. That becomes more important as distance increases. Just throwing numbers into a calculator a 215gr bullet launched at 3000 with a bc of .7 vs a 215 launched at 3000 with a bc of .4 has half the wind drift at 500 yards at 1100 ft. I am completely aware of all the millions of combinations of bullets, powders, and cartridges that we could throw into a calculator. I was just doing that to show bc does matter. I am also completely aware that usually, not always, lower bc bullets are lighter and will be at a higher mv. The fact is BC rules in the wind. [/QUOTE]
