308 Ballistics Chart & Coefficient

Article Posted: July 10, 2012

The following is a 1000 yard .308 ballistic chart that was created using our free online ballistic calculator and details all aspects of the bullets trajectory from the millisecond it leaves the barrel until the time it reaches the 1,000 yd mark. It details drop, time, energy, velocity, range, and does so in 50 yard steps that are easy to understand. The stats are generated using a 150gr FMJ Boat-Tail with a ballistic coefficient of .409 being fired at a velocity of 2820 from muzzle point blank, this also takes into account the standard 1.5" scope height, and a gun that has been sighted in at 100 yards. If your .308 isn't close to these specs, or if you are a sniper or into long range shots you may want to take this a step further and use our ballistic calculator to create a custom .308 ballistic chart to take into account variances. You can then also add atmospheric conditions and angles.

So what does the charting of the .308 Winchester's external ballistics tell us exactly? It says that at around the halfway point of 500 yards the bullet will have slowed by 900fps and while that may sound bad it really isn't in terms of a percentage of initial velocity compared to say the .223 Remington (would be 1481fps from initial 3214fps) or the 7.62x39mm (would be 1066fps from initial 2349fps). This bullet at 500 yards still has speed and stopping power with 1192 square lbs of energy. In fact the .308 Winchester 165gr bullet is traveling faster at 1000 yards than the .223 or 7.62x39mm at just 500 yds.
