I will quantify a few bullets below to demonstate the differences:

Bullet/BC Velocity Drop 10MPH 15MPH KE

Fail Safe/.391 3000 16" 13.6 20.4 1786
Accubond/.507 3000 14.6" 10.1 15.1 2115
Barnes X/.552 3000 14.2" 9.2 14.2 2213
Barnes X/.552 2800 16.5" 10.1 15.1 1902

Accubond/.588 282016.0 9.314.0 2217

The top 4 bullets are 180 Grain, the guns are zeroed at 250 yds and the 10 MPH and 15 MPH columns are wind drift at 400 yds. KE is also at 400 yards.

The BChas a small effect on Dropless than 2 inches at 400 yds but a big difference in wind drift up to 6.3 inches. Most hunters think wind drift is a function of bullet speed, but the BC is much more important than speed. You will notice that theBarnse bullet lauched at 2800 FPS actually has 5.3 inches less wind drift than the FailSafe lauched at 3000 FPS while still having more drop. The KE is also greatly affected by the BC.

You will notice the Accubond/.588 in bold. This a 200 grain bullet it is lauched 180 FPS slower than the Failsafe and has less KE at the muzzle yet has the same bullet drop, 6.4 inches less wind drift, and over 400 LBS more KE than the failsafe @ 400YDS. With a high BC you may be able to shoot a heavier bullet at a slower muzzle velocity and have the same trajectory, and a lot more KE on target. So much for light and fast bullets on long shots.

I am big fan of high BC bullets in case it is not obvious. The biggest advantage it offers is it minimized the effects of wind on that critical first shot.
