Knowing that bullets cast from moulds will have small dimensional differences when they harden, it is necessary to reduce such variations to improve the dimensional constancy.

This is possible with our roller, which improves also the roundness of the same balls, reducing to the minimum the casting feed-head. I

t is produced with steel, sanded and blued, with rectified disk and inside. The rolling operation is made by hands, rolling the disk inserted into the rollerbody, where a sufficient number of balls of the same caliber have been placed to cover the bottom.
