Quick Answer
Yes, you can use handloads in your semi-automatic rifle, but it requires careful consideration of the load's characteristics to ensure reliable functioning and minimize the risk of jamming.
Choosing the Right Handload for Semi-Automatic Rifles
When selecting a handload for your semi-automatic rifle, prioritize a powder burn rate that’s suitable for the rifle’s action and barrel length. For example, faster burn rates are best suited for shorter barrels and slower burn rates for longer barrels. A typical burn rate for a semi-automatic rifle is in the moderate to fast range, around 800-1000 ft-lbs of muzzle energy.
Reliability and Case Life
To ensure reliable feeding and extraction in a semi-automatic rifle, it’s essential to optimize the handload’s case life. This can be achieved by using a moderate to slow burn rate, a case that’s not too long or too short, and a bullet that’s not too heavy or too light. A good starting point for case life is to aim for a case length of around 2.80-2.82 inches, and to use a bullet that weighs between 150-180 grains. Additionally, consider using a primer that’s specifically designed for semi-automatic rifles, as they tend to be more consistent and reliable.
Testing and Load Development
Before running your handload in the field, it’s crucial to test it in a safe and controlled environment to ensure it’s functioning reliably. This involves shooting a series of rounds through a chronograph to measure velocity, and inspecting the cases for proper extraction and ejection. It’s also a good idea to start with a small batch of 20-50 rounds and gradually increase the quantity as you refine the load. Using a load development process such as the “starting light” method can help you identify potential issues early on and make adjustments as needed.
