Lyman has redesigned the 55 Powder Measure for both smokeless and black powder. A must for black powder cartridge silhouette and cowboy action shooters. The internal metering bars rotate in a non-sparking brass sleeve. A large non-static aluminum powder reservoir holds a pound of black powder. The unique three-slide adjustment bars are the key to consistent accuracy from small pistol charges to the largest rifle charges with accuracy to a fraction of a grain. Mounts on the bench or directly on a press or powder measure stand and includes a 7/8 x 14 adapter.
