BPI Original Buffer is used in almost all types of shotshell loads, from 10ga to .410. A proprietary blend of buffering materials marginalize density effect and create conditions necessary for optimal pattern density. Original Buffer cushions the shot payload during critical stages of transition through areas of constriction, reducing disturbance and chaos during initial stages of pattern development.
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%.
