Quick Answer
For open fields, I recommend the .270 over .308 due to its flatter trajectory and less bullet drop at longer ranges.
Ballistic Advantage
The .270 Winchester offers a slight advantage over the .308 Winchester in terms of ballistic performance. With a slightly faster bullet velocity and a flatter trajectory, the .270 excels at longer ranges. For example, at 400 yards, a 130-grain .270 bullet will drop only 36 inches, while a 150-grain .308 bullet will drop 51 inches. This makes the .270 a better choice for hunting in open fields where shots may be taken at longer distances.
Hunting in the Real World
In reality, most whitetail hunting occurs at ranges under 200 yards. However, understanding the ballistic differences between cartridges can help you make informed decisions. For hunting in open fields, the .270’s flatter trajectory can be a significant advantage. Additionally, the .270’s higher muzzle velocity (around 3,000 fps vs. 2,700 fps) means less time for the bullet to drop, allowing for a faster follow-through and reduced error. When hunting in open fields, take advantage of the .270’s ballistic characteristics to make more effective shots.
Practical Considerations
While the .270 may offer a slight ballistic advantage, it’s essential to consider other factors when choosing a cartridge. The .308 is a more popular and widely available choice, making it easier to find ammunition and rifles. Additionally, the .308’s heavier bullets provide more kinetic energy, which can be beneficial for larger game. Ultimately, the choice between the .270 and .308 comes down to personal preference and specific hunting needs. If you’re hunting in open fields and prioritize a flatter trajectory, the .270 may be a better choice.
