Although velocity is desired when shooting long distance, a bullet's BC actually has more effect on wind drift and retained
velocity then actual muzzle velocity does (within reason). As an example (see pic) you can take a 22-250 and load it up to 4000 fps with a poor BC bullet like a 40gr V-Max, then take the same round but load it up to 3700fps with a 55gr Vmax which has a better BC number. Even though the heavier but sleeker bullet started off 300 fps slower, by 300yds it is going faster by retaining it's velocity much better (which makes for less time of flight as distances increase). It's also much less effected by a 10mph crosswind. My .204 is a good example. It shoots a 35gr Berger great...but that little bullet has a terrible BC and is really pushed around by the wind on any shots over 200 (very few when we're talking coyotes). I can load up a 39gr BK 100fps muzzle velocity slower and have it drift half as much in the wind due to it's relatively good BC.
I also somewhat disagree with not believing the charts...they are usually pretty accurate. The problem usually come from over/under estimating wind speed...it might be blowing more or less near the target...lots of variables. Truthfully, most shots we take in the field are in ranges where all this stuff is moot. Well, at least myself and all the guys I hunt with. Every so often I'll have to apply a bit of Kentucky windage but for most of my field shooting, bullet BC plays little role.
