Rifle cant error is the tendency of a rifle to move in an arc when fired. This can cause missed shots at long distances due to incorrect shot placement. To prevent rifle cant error, keep the barrel of your rifle straight throughout the firing process. This will help ensure that your shots hit their intended targets.

It is important to maintain a consistent trajectory and aim point when shooting long-range. By keeping the barrel of your rifle straight, you can improve your shooting accuracy and reduce the risk of making misfires.

5.The Barrel Length And Weight

The Barrel Length And Weight

Long and heavy rifle barrels are critical for long-range shooting. A long barrel will help to reduce the effects of rifle cant error, while a heavy barrel will help to minimize recoil felt by the shooter, which can improve shooting accuracy. Long and heavy barrels are also important for reducing muzzle noise and increasing range. The right barrel length and weight depend on the type of shooting and shooting range. It is important to test various options to find the best combination for you and your shooting style.

6.Cartridge Selection

Cartridge Selection

When selecting a cartridge for long-range shooting, it is important to consider the rifle’s cant error. This is the vertical angle of the trajectory of a bullet as it leaves the barrel and generally ranges from 0 to 20 degrees. It is often expressed as a fraction, such as 1/2 or 3/4. The best long-range cartridges have low cant errors, allowing tight groups when shooting long distances.

In addition to cartridge selection, regularly practicing to improve your shooting skills is vital. You can gradually build up your shooting skill and accuracy over time by shooting regularly. Besides, match the cartridge to the barrel’s caliber and twist rate to ensure accuracy when shooting at long range.

7.Bullet Selection

Bullet Selection

Bullet selection is one of the most important factors when shooting long distances. The bullet you choose will impact your accuracy and range. There are various factors to consider when selecting the right bullet for your gun and target. It is important to select a bullet with the right weight and shape for your gun.

Additionally, if you are shooting at long range in cold conditions, you may want to use a premium bullet that is optimized for sub-zero temperatures. When choosing the right bullet for your long-range shooting, consult an expert for help.

Tips On Long-Range Shooting Rifles Cant Error

Tips On Long-Range Shooting Rifles Cant Error

A rifle cant error is a measurement representing the angle of the rifle’s barrel relative to the plane of its stock. A cant error can be measured using a vernier caliper or a digital angle-measuring tool. A high-quality rifle will have a low cant error, which is ideal for long-range shooting.

A rifle cant error is typically expressed as a percentage, with higher numbers indicating more deviation from the perpendicular (90 degrees). A low cant error suggests that the firearm’s barrel and stock are aligned properly and free from defects or damage. High-quality rifles typically have low cant errors, allowing for accurate long-range shots.

When shooting long-range, you should know the importance of rifle cant error. This is caused by the angle of elevation of the shooter when firing the rifle. To reduce the chance of this error, aim for the target’s center mass and adjust your elevation using a scope-mounted rear sight. This will compensate for any windage error that may occur.

Also, keep your eyes open for different positions and distances to increase your chances of hitting targets. Finally, shoot at a range as close as possible to the target to minimize the effect of wind and bullet drop. Following these tips can improve your long-range shooting abilities and achieve success at any range.


With this, you’re well-prepared to tackle long-range shooting. Remember that distance is your enemy, and precision is your savior. If you practice, it will become easier for you to hit targets. And the more you practice, the better you’ll get. Try to identify any external factors that might cause shooter error (such as the range of the target, wind, etc.) and work on them.

There’s a lot of misconception surrounding long-range shooting, but these simple steps can help you improve your accuracy. Next time you’re out for long-range shooting, try following these external ballistics tips to ensure an accurate shot.
