The Redding T-7 Extra Turret is a great item to have on hand if you frequently use your Redding T-7 Turret Press (Item RB67000). This tool features a 7-station turret head, which can turned to set your next reloading die in place. The more turrets you have, the more easily you can switch between different calibers. If you are the type of reloader who uses multiple caliber sizes with your Redding T-7 Turret Press, you may want to have a few extra turrets on hand. Simple load the die in the turret, then, when you are ready to switch calibers, swap out the turret head. It is that simple.
