Next, you’ll find information about suitable powder brands and types. Nosler will identify specific powders that have been tested and verified for safe and accurate performance with their bullets. This list is a starting point; it is never recommended to try alternative powders unless data from reputable sources is available. Primer types, also known as ignition, are equally important. Nosler will recommend specific primer brands and types designed to ignite the chosen powder consistently. Cartridge case types will also be listed in the load data. Using the correct case for the load ensures correct dimensions.
Cartridge overall length, or COAL, is a critical dimension. COAL defines the total length of the loaded cartridge. COAL affects the internal ballistics of the round, influencing pressure and velocity. COAL specifications, carefully determined during testing, ensure bullets seat properly, allowing optimal performance. The data will clearly state the optimal COAL to aim for. Another important element to consider is the starting and maximum load data, measured in grains. This information provides the range within which it is safe to load the cartridge. Never exceed the maximum load or go below the starting load. The data provides a series of loads, with corresponding powder charges, that a reloader can test in the field.
Velocity data, expressed in feet per second, shows the expected muzzle velocity of the loaded round. While actual results can vary based on factors like temperature and barrel length, the data provides a benchmark for the expected performance. Finally, pressure, usually displayed in either CUP (Copper Units of Pressure) or PSI (pounds per square inch), is an essential element of the data. Pressure reflects the internal force generated within the cartridge when the powder ignites. Stay well within the data’s parameters and be aware of pressure. Understanding the interaction of these components, the proper application of this information, and meticulous adherence to these specifications, will bring the reloader success.
