[QUOTE="257 Blackjack, post: 1461520, member: 106220"] If the game is uncertain conditions where the first or second shots count, reducing the effects of Wind Deflection is huge. The other variables are now pretty determinable with good equipment. For Long Range Hunting, Blind Stages in Tactical / Practical matches, and ELR. BC is a major performance factor. A group of bullets BC deviation over x number of required shots in a certain discipline is huge too and while folks focus on SD of their MV there is also bullet to bullet standard deviation as well, so consistency shows up at longer and longer ranges. That being said, a more efficient bullet will offset a certain portion of that deviation. Of course there are short range and midrange target cats who know or have a lot of evidence to support that lower BC flat base bullets shoot about as accurately as you can shoot a rifle but if your interest or applications reach past 800-1500+ yards it's hard to give up a nice boattail. The old paradigm was Muzzle Velocity:Trajectory. More and more field style shooters are thinking about shot control and prediction power which is recoil:wind deflection and how those two work together. Still many chase MV trying to solve the trajectory and wind problem adding unnecessary recoil to the equation when much of that efficiency could be designed in, a la BC. I guess you can see how I lean. Efficiency across the board for me. [/QUOTE]
