LAMBRO hunting cartridges with semi buckshot represent the epitome of the art of loading.
Due to their large size, shots loaded with the conventional volumetric method result to weight fluctuations. Star crimp with big shots may create bumps and the cartridge will become stuck in the chamber. This is not a problem with a LAMBRO cartridge.
At LAMBRO all shot sizes over 4mm are loaded by counting instead of the conventional method of volumetric loading. In this way each cartridge contains the same number of shots has a perfect good closure, stability and high performance.
