Popis
Norma 202 is a medium burn rate propellant specifically designed for precision rifle applications. This powder is well-regarded for its consistent performance in a variety of calibers, offering stable pressures and velocities essential for competitive shooting and hunting applications. Norma 202 is typically employed in cartridges like the .308 Winchester and .30-06 Springfield, where its burn characteristics provide optimal energy delivery and accuracy. The physical form of Norma 202 is typically a fine-grained extruded powder, ensuring smooth metering through various powder measures, which is beneficial in maintaining uniform charge weights across numerous loads. In terms of temperature sensitivity, Norma has refined the formulation of 202 to ensure minimal variance in performance under different environmental conditions, enhancing reliability across a wide range of settings. Handloaders appreciate 202 for its ability to develop accurate and efficient loads with reduced copper fouling. Overall, it's a trusted choice for consistent results in medium to large rifle calibers.
