This aluminum Russian bullet mold casts a single hollow point bullet with a flat base and a hole for attaching the bullet to a plastic gas seal. Two plugs are included. The segmented option casts a 530 grain slug. The unsegmented is 556 grains. This is a bore riding slug that measures about .725. It can be distinguished from the Flybot easily because it has 2 bore riding bands not 3 and they are much thinner. This is thought to reduce recoil. Includes box and instructions. No bullets are included.
