Accurate 8700 (8lb)

An extremely slow-burning, double-base ball-type rifle powder, which is the accurate slowest powder. It was originally developed for the.50 Browning (12.7mmx99 Nato). This powder delivers optimum performance in heavily necked-down large capacity calibers such as the.257 Weatherby Magnum,.264 Win Mag, and 7mm RUM. This powder is so slow that even at maximum and compressed loading densities, it is virtually impossible to cause any overpressure.
