The new 2017 Sporter and Hunter models have a newSpeedlock adjustment system that now stops on both maximum length of pull and maximum height adjustment on the cheek piece.
This new system is also installed on the 2017 Berserk models. The new system is stronger than the previous adjustment system but we still set the maximum caliber to a standard 375H&H load (300 grain bullet @2500 f/s or 762m/s (6321Joule)). Remember, when shooting these calibers you must always glass bed your rifle on the laminate models.
