Carlson's Black Cloud choke tube sets can be used with any lead, HeviShot or steel shot, but they are optimized for phenomenal performance with Federal Black Cloud ammunition. The extended tube is titanium coated, which helps the FliteControl wad in the Black Cloud ammo perform downrange with minimal build-up in the choke. This allows the FliteStopper shot to do it's job, increasing your take in the field.
The long range tube should not be used with steel shot larger than BB or any steel shot faster than 1550 fps. The Mid Range tube can be used with all shot sizes and velocities.
