These chokes are specifically designed to get the most performance from Federal's Black Cloud Ammunition, but still perform extremely well with other steel shotshells. The Extended tube is constructed of a Titanium-coated steel, and comes in Mid Range and Long Range models. 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.
