Berger Bullets Reloading Information [verified] -

When developing a load, the reloader must first determine the Cartridge Overall Length (COAL) at which the bullet contacts the rifling (touching the lands). Once this baseline is established, Bergers are typically loaded between 0.010 inches off the lands to as much as 0.150 inches off the lands. A common starting point for Bergers is a jump of 0.020 to 0.030 inches. However, the unique characteristic of Bergers is their tolerance for longer jumps. Because of the Hybrid ogive, they can often maintain accuracy even when seated significantly deeper in the case. This flexibility allows reloaders to tune the load to fit their specific magazine length constraints or to adjust pressure curves. It is generally recommended to test seating depth in increments of 0.010 or 0.015 inches to identify the specific node where the rifle harmonizes with the bullet.
