BPI - Mix #47 Shotshell Buffer 1/2 lbs
Years ago, Ballistic Products developed this special combination of ingredients to handle the difficulties of steel and very large pellets. As an absolute success, Mix 47 has been used for all buffering applications since. Minimum pressure increase, maximum pattern density, and round pellets are the result with Mix 47. Mix 47 stabilizes steel shot pellets and keeps patterns dense, even under the stress of 1500 fps velocities!
