Quick Answer
Evaluate new powder brands for handloading by considering their burn rate, pressure curve, and overall performance in various rifle calibers. Test the powder in a well-equipped laboratory setting with a chronograph and pressure gauge. Compare the results to established powder brands.
Choosing the Right Test Rifle
When evaluating new powder brands, it’s essential to start with a rifle that’s well-suited for the task. A bolt-action rifle with a consistent chamber and a high-quality barrel is ideal. For example, a Remington 700 in .308 Winchester or a bolt-action AR-15 in .223 Remington would be excellent choices. These rifles provide a stable platform for testing powder performance.
Laboratory Testing
In a well-equipped laboratory setting, you can accurately measure the performance of new powder brands using a chronograph and pressure gauge. Set up a chronograph 10-15 feet from the rifle’s muzzle and take multiple readings to ensure accuracy. Use a pressure gauge to monitor the rifle’s pressure curve, which should be within safe limits (typically below 55,000 psi). Take note of any excessive pressure spikes or inconsistent readings.
Real-World Testing
After laboratory testing, it’s essential to evaluate the new powder brand in real-world hunting conditions. Use the same rifle and load in a live fire setting, taking note of the bullet’s trajectory, accuracy, and expansion. Compare the results to established powder brands and take into account any differences in rifle performance or environmental conditions. This will give you a more comprehensive understanding of the new powder’s performance and help you make informed decisions about its use in the field.
