Can Handloaded Ammo Outperform Factory Loads for Accuracy?

Choosing the Right Components

When it comes to handloading for accuracy, selecting the right components is crucial. For instance, a .308 Winchester rifle might use a 168-grain Sierra MatchKing bullet, which has a G7 BC of 0.734. This bullet performs exceptionally well at long distances and is often used in precision rifle shooting. However, for shorter ranges, a heavier bullet like the 175-grain Hornady A-Max might be a better choice, with a G7 BC of 0.625. The right bullet choice can make a significant difference in accuracy.

Load Development and Optimization

Developing a precise handload requires a systematic approach to testing and iteration. Start by selecting a base load with a known powder charge and seating depth, then incrementally adjust these parameters to find the optimal combination. For example, a .308 Winchester rifle might use 44.0 grains of H1000 powder with a 168-grain Sierra MatchKing bullet seated at 2.820 inches from the lands. By adjusting the powder charge in 0.1-grain increments, the hunter can find the optimal load for their rifle. In this case, 44.5 grains of H1000 resulted in a 0.5-inch group at 100 yards, while 44.0 grains yielded a 0.7-inch group.

Seating Depth and Bullet Position

The seating depth of the bullet can also significantly impact accuracy. A bullet seated too far forward can cause inconsistent ignition, while one seated too far rearward can result in inconsistent expansion. By carefully measuring and adjusting the seating depth, hunters can optimize the bullet’s position within the case and achieve better accuracy. A general rule of thumb is to seat the bullet 0.010 inches off the lands for optimal performance, though this may vary depending on the specific rifle and cartridge.
