Can Handloads Compensate For Inconsistent Factory Ammunition?

Understanding Factory Variance

Factory ammunition is produced in large quantities and often involves compromises in order to meet mass production requirements. This can result in inconsistent performance, including variations in velocity, pressure, and accuracy. For example, a 6.5 Creedmoor cartridge may have a stated velocity of 2,800 feet per second, but actual velocities can range from 2,750 to 2,900 feet per second. This variance can be significant for long-range shooting or hunting applications.

The Benefits of Handloading

Handloading allows shooters to carefully control the variables that affect bullet performance. By measuring and adjusting factors such as bullet weight, case length, and powder charge, handloaders can achieve consistent and predictable results. For example, a handloader may load a 6.5 Creedmoor cartridge with a bullet weighing 130 grains, a case length of 2.260 inches, and a powder charge of 43.5 grains of H4350. This consistent loading can result in tighter groups and more reliable performance. To achieve this level of control, handloaders typically need to start with a reliable and accurate powder burn rate, such as a 4350 powder class, which can provide a more consistent range of velocities.

Practical Application

To compensate for inconsistent factory ammunition, handloaders should start by measuring and recording the actual performance of their factory loads. This can involve using a chronograph to measure velocity and a target to measure accuracy. Once the variance is understood, the handloader can begin to adjust the loading variables to achieve more consistent results. For example, if a handloader finds that their factory 6.5 Creedmoor cartridges are producing velocities ranging from 2,750 to 2,900 feet per second, they may choose to load their own cartridges with a more consistent powder charge, such as 43.5 grains of H4350, to achieve a more predictable velocity.
