A bullet’s journey from the muzzle to its goal is influenced by various elements. Let’s unpack just a few of probably the most essential components:
- Ballistic Coefficient (BC): It is a numerical illustration of a bullet’s means to beat air resistance. The next BC signifies a bullet that can lose velocity extra slowly, permitting it to journey additional and retain extra power.
- Muzzle Velocity: The pace at which the bullet leaves the muzzle is a significant determinant of its trajectory. Larger muzzle velocities usually translate to flatter trajectories and fewer bullet drop over a given distance, although that is typically paired with a trade-off in recoil.
- Wind Drift: Wind is the enemy of precision at lengthy vary. Even a light-weight crosswind can considerably push a bullet off beam. Correct wind estimation and the power to compensate for it are important expertise.
- Bullet Drop: Gravity relentlessly pulls each bullet downward. The longer the bullet’s flight time, the extra dramatic the drop. Because of this you could constantly account for bullet drop at prolonged ranges by adjusting your scope.
- Exterior Ballistics: This encompasses all of the elements influencing a bullet’s path, together with atmospheric circumstances corresponding to temperature, humidity, and air density, which impacts bullet’s flight path. Coriolis impact, the impact of the earth’s rotation on the bullets trajectory, additionally turns into an element at excessive ranges.
The appropriate tools is important for long-range capturing. rifle with a constant barrel, a high-quality scope with correct changes, and a secure platform for capturing (corresponding to a bench or bipod) are important for achievement. Moreover, the ammunition, all the way down to the precise bullet weight and design, performs a major position.
The .308 Winchester: A Nearer Examination
A Temporary Historical past

Analyzing the Efficiency of the .308 at Lengthy Vary
Understanding the Numbers
To really assess the .308’s long-range functionality, we have to look at efficiency knowledge. This info will illustrate the impression of bullet choice, velocity, and environmental circumstances on the trajectory of a .308 bullet.
Totally different bullet weights have totally different ballistic profiles. For instance, a 175-grain Sierra MatchKing bullet will doubtless have the next ballistic coefficient than a 150-grain searching bullet. This implies it’s going to retain its velocity and power higher downrange. Take into account the next hypothetical knowledge, conserving in thoughts that precise outcomes can differ based mostly on particular load, rifle, and environmental circumstances:
*(Please notice: I can not present real-time, exact ballistic tables right here, as this may require a ballistic calculator and continually up to date knowledge. Nonetheless, I’ll present examples that can assist you perceive the idea)*
Instance Knowledge
Let’s assume now we have two hundreds utilizing a .308 Winchester with a 100-yard zero:
- Load 1: 175-grain Sierra MatchKing, Muzzle Velocity: 2600 toes per second (fps), BC: .500
- Load 2: 168-grain Hornady A-Max, Muzzle Velocity: 2700 fps, BC: .475
Utilizing a ballistic calculator (extremely advisable for real-world use), we may see one thing like the next:
Approximate Bullet Drop (inches):
| Distance (Yards) | Load 1 (175gr) | Load 2 (168gr) |
|---|---|---|
| 300 | -2.0 | -2.0 |
| 500 | -18.0 | -19.0 |
| 600 | -31.0 | -33.0 |
| 800 | -69.0 | -74.0 |
| 1000 | -126.0 | -136.0 |
Approximate Wind Drift (inches) with a 10mph crosswind:
| Distance (Yards) | Load 1 (175gr) | Load 2 (168gr) |
|---|---|---|
| 300 | 3.5 | 3.8 |
| 500 | 9.0 | 10.0 |
| 600 | 13.0 | 14.5 |
| 800 | 24.0 | 27.0 |
| 1000 | 39.0 | 43.0 |
Approximate Retained Power (foot-pounds):
| Distance (Yards) | Load 1 (175gr) | Load 2 (168gr) |
