Completely different bullet weights have totally different ballistic profiles. For instance, a 175-grain Sierra MatchKing bullet will doubtless have a better ballistic coefficient than a 150-grain searching bullet. This implies it can retain its velocity and vitality higher downrange. Contemplate the next hypothetical information, holding in thoughts that precise outcomes can fluctuate primarily based on particular load, rifle, and environmental situations:
*(Please observe: I can’t present real-time, exact ballistic tables right here, as this is able to require a ballistic calculator and consistently up to date information. Nonetheless, I’ll present examples that will help you perceive the idea)*
Instance Information
Let’s assume we now have two masses 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 really helpful for real-world use), we might 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 Vitality (foot-pounds):
| Distance (Yards) | Load 1 (175gr) | Load 2 (168gr) |
