[QUOTE="Fiftydriver, post: 145846, member: 10"] I also use 0.740 BC for the 169.5 gr ULD RBBT. Don;t mess with the lighter ones, no reason to for what I use the 270 for. This BC works very well for muzzle velocities from 3200 to 3400 fps at 3300 ft altitude. I have tested out to 2200 yards with this bullet and from dial up figures this BC holds pretty **** close out to that range so I figure its a good average BC for out to extreme range. Do not know if the BC drops with lower muzzle velocities but I doubt that it does much. Again, these BC numbers are what I need to put into my Exbal program to get the predicted bullet flight to match actual bullet flight. It may not be the pure scientific BC but its what I have to use if I want to hit what I am shooting at at long range. Kirby Allen(50) [/QUOTE]
