[QUOTE="speedengineer, post: 1822388, member: 112986"] And, some more info to go with the image I attached 2 posts above... For long range hunting, wind uncertainty will probably be the biggest range limiter for responsible hunting, ya? Let's pretend for some particular animal you're hunting, you'll only take a shot if you have less than +/- 5 inches of impact uncertainty from your point of aim due to wind - aka a 10" kill zone, and ignoring all other uncertainties and you have 0moa shooter accuracy... Furthermore, say you can make your wind call accurate to +/- 5mph (with a 90 degree cross wind which is the worst case scenario). The maximum range you can take a shot and know you'll hit your 10" target, provided the above conditions, for the trajectories of the bullets previously posted are: Federal TA - 505yd Hammer Hunter - 515yd ABLR - 535yd ELDx- 535yd EOL- 540 yd ELDm - 560yd (not a real hunting bullet?) 30-06 High BC - 465yd 30-06 Low BC - 375yd So yes, higher BC buys you a little bit of extra yardage, but not much. It seems like you want to stay above a BC of 0.500, and then just select the bullet that shoots most accurately in your rifle, and has the terminal performance that you think meets your requirements.
