Quick Answer
The .270 Winchester's relatively flat trajectory makes it well-suited for longer shots, although bullet drop can still be a concern at extreme ranges. With proper ballistic calculations and a suitable scope, hunters can manage bullet drop and hit their mark at longer distances. This rifle caliber is a popular choice for whitetail hunting.
Ballistic Characteristics of the .270
The .270 Winchester’s flat trajectory is due to its relatively low ballistic coefficient (BC) and a high velocity. The average BC for a .270 bullet is around 0.5, which is lower than the .308 (around 0.5-0.6) but higher than the 6.5mm (around 0.4-0.5). This means that the .270 will drop less over a given distance compared to the 6.5mm, but more than the .308. For example, at 400 yards, a .270 bullet will drop around 36 inches, while a 6.5mm bullet will drop around 43 inches, and a .308 bullet will drop around 30 inches.
Managing Bullet Drop with the .270
To manage bullet drop with the .270, hunters should use a scope with a magnification of at least 4x, and ideally 8x or higher. This will allow for precise adjustments and a clear view of the target. Hunters should also use ballistic software or a calculator to determine the point of impact at longer ranges. This can be done by inputting the rifle’s characteristics, the type of bullet being used, and the distance to the target. By making the necessary adjustments, hunters can compensate for bullet drop and hit their mark at longer distances. For example, at 500 yards, a .270 bullet will drop around 56 inches, so hunters would need to adjust their aim down by around 4.7 MOA (minute of angle) to compensate for this drop.
