Carlson's Black Cloud choke tubes are specifically designed to get the most performance from Federal's new Black Cloud Ammunition, but perform extremely well with other steel shotshells. The Extended tube is constructed of a Titanium-coated steel, the titanium coating helps the uniquely designed FliteControl Wad in the Black Cloud ammunition perform downrange with less build-up in the choke and allows the Flitestopper shot to do its job this increasing your take in the field. The Mid Range model can be used with all steel shot sizes, and with ammunition that exceeds 1550 fps. Black Cloud ammunition has been designed to be used with choke tubes that do not use porting or wad stopping devices.
