- Bullet weight: Heavier bullets generally require larger powder charges.
- Powder type: Different powders burn at different rates, requiring adjustments to the charge weight.
- Primer type: Primer type can slightly affect ignition and pressure.
- Case capacity: Variations in case capacity can impact pressure.
- Rifle twist rate: The twist rate of your rifle's barrel influences bullet stability.

COL refers to Cartridge Overall Length. Always measure your COL carefully using a case gauge.
Monitoring Pressure Signs
While reloading, carefully monitor pressure signs. Excessive pressure can manifest as:
- Difficult bolt lift: A noticeably harder-than-usual bolt lift.
- Flat primers: Primers that are flattened or have a significant crater.
- Excessive case head expansion: Cases noticeably swollen near the base.
- Unusual sounds or recoil: Noticeably louder or sharper sounds, or more intense recoil than normal.
If you observe any of these signs, immediately cease reloading and investigate the cause.
Resources for Further Learning
Reliable reloading manuals provide comprehensive and up-to-date information on safe reloading practices and load data. Many websites and forums dedicated to reloading also offer valuable resources, however, always prioritize information from reputable sources and manufacturers. Remember, safety should always be your top priority when reloading ammunition. Improper reloading can lead to serious injury or damage.
