This video explains the critical 'plunk test' for handgun reloading, emphasizing that cartridge overall length (COL) must be determined for each specific firearm and projectile combination, not just by book values. The plunk test involves chambering a loaded cartridge in the firearm's barrel and measuring the maximum safe COL. Subtracting a small margin from this measurement ensures reliable feeding and prevents the projectile from engaging the rifling, which can cause malfunctions. This technique is crucial for handguns with shorter leades, such as CZ models, to avoid issues like slides hanging out of battery.
