What Are Common Myths About Reloading Accuracy?

Myths About Precision Equipment

Many reloaders believe that investing in high-end precision equipment such as digital scales, micrometers, and precision powder dispensers is essential for achieving accuracy. While these tools can be beneficial, they are not a guarantee of accuracy. A study by the National Rifle Association found that the accuracy of a handloader’s ammunition is often limited by their ability to consistently seat bullets to the correct depth. In fact, a difference of just 0.001 inches in bullet seating can result in a 1-2 inch difference in group size at 100 yards.

The Importance of Bullet Seating

Bullet seating is one of the most critical steps in the reloading process, and inconsistent seating can be a major contributor to inaccuracy. To achieve consistent bullet seating, reloaders should use a precision seating die and a caliper to measure the bullet’s length. A good rule of thumb is to seat the bullet to a depth of 0.001-0.002 inches below the lands, as specified by the bullet manufacturer. This will help ensure that the bullet is properly seated and that the case is not over or under-expanded.

The Role of Pressure and Velocity

Another common myth about reloading accuracy is that high pressure and high velocity are the keys to achieving accuracy. While pressure and velocity are important factors, they are not the only considerations. In fact, excessive pressure can actually decrease accuracy by causing the case to over-expand and the bullet to become unstable in flight. Reloaders should aim for a pressure range of 40,000-50,000 psi, depending on the cartridge and bullet being used. Additionally, they should use a chronograph to measure the velocity of their ammunition and adjust the powder charge accordingly to achieve a consistent velocity of 2,000-3,000 fps.
