Quick Answer
A magnum primer or a large rifle primer works best for .35 Whelen handloads, providing consistent ignition and reliability. Look for primers with a high energy output, such as Federal 210M or CCI Magnum. These primers are specifically designed for large rifle cartridges and can handle the increased pressure of the .35 Whelen.
Choosing the Right Primer
When selecting a primer for your .35 Whelen handloads, consider the cartridge’s high-pressure nature. A magnum primer or large rifle primer can handle the increased pressure, ensuring consistent ignition and reliability. Look for primers with a high energy output, such as Federal 210M or CCI Magnum.
Primer Options for Handloaders
For handloaders, Federal 210M and CCI Magnum primers are popular options. These primers offer high energy output and consistent ignition, making them well-suited for the .35 Whelen cartridge. When bench testing, consider using a chronograph to measure the velocity of your handloads with these primers.
Maximizing Performance
To maximize performance with your .35 Whelen handloads, use a consistent powder charge and primer. This ensures that the primer ignites the powder reliably, producing consistent results. Additionally, consider using a large rifle primer with a high energy output to ensure the primer ignites the powder quickly and consistently.
