All the experience we gained over the years of production of the Profi Hunter cartridge was taken into account when developing Siberia. All comments and wishes of consumers were taken into account. A lot of work has been done with hunting groups to get real, not laboratory-based test results only. The patrons were tested in various climatic conditions.
These cartridges are assembled using imported propellants; for each type of shot, its own grades of propellant and weights are selected, which allow to fully realize the set task - to provide the required speed, pressure, and penetrating ability.
