Whereas a rifle barrel is aligned with the shooter’s sight, gravity constantly pulls the bullet downward from the moment it leaves the muzzle. The diploma to which the bullet drops relies upon upon quite a lot of elements.
This is a simplified chart illustrating the estimated bullet drop and wind drift for a .270 Winchester 150-grain bullet with a muzzle velocity of roughly 2,850 ft per second. Keep in mind that real-world outcomes can change primarily based on environmental elements, and the bullet kind itself, this chart is designed to be a common guideline.
This chart assumes the rifle is zeroed at 100 yards, with a ten mph crosswind.
| Vary (Yards) | Bullet Drop (Inches) | Wind Drift (Inches) |
|---|---|---|
| 0 | 0 | 0 |
| 100 | 0 | 0 |
| 200 | -2.6 | 1.7 |
| 300 | -9.4 | 4.0 |
| 400 | -21.7 | 7.2 |
| 500 | -40.4 | 11.0 |
Rationalization of the Chart
This desk illustrates the anticipated bullet drop in inches at totally different distances. For instance, at 200 yards, the bullet is predicted to drop roughly 2.6 inches under the road of sight when the rifle is zeroed at 100 yards. The chart additionally demonstrates the impression of wind drift, showcasing how a ten mph crosswind can push the bullet sideways, even at comparatively shut ranges. The longer the vary and the upper the wind pace, the larger the impression on the bullet’s flight.
The values are calculated underneath ultimate situations, nevertheless, it might present a substantial amount of perception on the bullet’s flight traits.

Distance to Goal
The space to your goal is essentially the most essential issue affecting bullet drop. As the space will increase, the bullet spends extra time in flight. The longer the bullet is airborne, the extra time gravity has to tug it downwards, resulting in a extra important drop.
The Significance of Ballistic Coefficient
The ballistic coefficient (BC) is a measure of a bullet’s capacity to beat air resistance. A better BC signifies that the bullet is extra aerodynamic and can resist air drag extra successfully. This ends in a flatter trajectory and fewer bullet drop over a given distance. The 150-grain bullets used within the .270 sometimes have a decent BC, contributing to their fame for efficient long-range efficiency.
Muzzle Velocity’s Impression
Muzzle velocity, the pace at which the bullet leaves the barrel, additionally closely influences trajectory. A better muzzle velocity usually ends in a flatter trajectory and fewer bullet drop over a given distance. The .270 Winchester is thought for its comparatively excessive muzzle velocities, enhancing its long-range capabilities. The quicker the bullet travels, the much less time gravity has to have an effect on it throughout its flight.
Coping with Environmental Circumstances
The setting itself has a notable impression on how your bullet strikes via the air. You should contemplate these elements.
Air Density
Air density impacts the power of drag on the bullet. Temperature, altitude, barometric strain, and humidity affect air density. Larger air density ends in larger drag, which is able to improve bullet drop, whereas decrease air density permits the bullet to journey farther.
Wind’s Impact
Wind is one other influential issue to contemplate. Wind can push a bullet sideways, inflicting what is named “wind drift.” The larger the wind pace, the larger the drift. A crosswind will push the bullet off its course, whereas a headwind or tailwind will affect the bullet’s velocity, however have a much less lateral impact.
Elevation’s Affect
When you’re taking pictures at a goal that’s increased or decrease than your taking pictures place, you may additionally must account for elevation variations. When taking pictures uphill, the bullet will expertise much less drop, whereas taking pictures downhill will improve the drop.
Making Use of Bullet Drop Data
Successfully using the chart, and understanding the opposite elements concerned, is essential for constant accuracy.
Zeroing Your Rifle
Essentially the most basic step is to zero your rifle. Zeroing is the method of adjusting your sights in order that the bullet strikes your meant level of impression at a selected distance. The frequent zeroing distance for .270 rifles is usually 100 yards or 200 yards. This ensures that the bullet will hit very near your level of purpose at that distance.
Adjusting for Vary
To compensate for bullet drop at longer distances, you may have two choices.
First, you should utilize the reticle in your scope to purpose increased. This is named “holdover.” Many scopes characteristic hash marks on the reticle (typically known as “mil-dots” or different range-finding designs). These aid you to visually estimate and compensate for bullet drop at totally different ranges.
Second, you should utilize a scope with adjustable turrets. One of these scope lets you dial within the precise adjustment wanted for the space you might be taking pictures.
