Quick Answer
For handloading the 6.5-284 Norma, CCI 200 and 201 large rifle primers are considered to be the best options due to their consistent ignition and reliable burn characteristics.
Primer Selection Criteria
When selecting primers for the 6.5-284 Norma, look for large rifle primers with a consistent ignition and reliable burn characteristics. In this caliber, CCI 200 and 201 large rifle primers are the most popular choices among handloaders. These primers have a proven track record of consistent performance, and their smaller flash signature makes them ideal for target shooting.
Primer Reliability and Performance
The 6.5-284 Norma is a high-pressure cartridge, and a reliable primer is essential to ensure consistent ignition and prevent primer pocket erosion. Look for primers with a high-temperature sensitivity, as these will provide a more consistent burn rate and reduce the risk of primer pocket erosion. CCI 200 and 201 primers meet these criteria, with a temperature sensitivity of 30°F (16.7°C) or greater.
Primer Seating Depth and Load Development
When handloading the 6.5-284 Norma, it’s essential to develop a load that balances accuracy, velocity, and reliability. The primer seating depth can have a significant impact on the overall performance of the cartridge. Aim to seat the primer to a depth of 0.060" to 0.070" from the cartridge case head, depending on the specific load and cartridge design. This will ensure consistent ignition and prevent primer pocket erosion.
