Buffer 47 for steel shot and large buckshot loads. The materials in Mix #47 reduce pellet rebounding and ease the critical transition of hard pellets through the choke. Steel shot and large pellets put huge demands on buffer, particularly when the loads are designed for high velocity.
DO NOT BUFFER LOADS THAT DO NOT CALL FOR BUFFER IN THE LOAD DATA.
Adding buffer to a load can increase the pressure by 20 – 30%.
