Instead of buying the official MEC short kit these tools do a great job at a lower price and are easier to use and come in a greater range of sizes.
The parts just fit into the existing stations on the base plate and are held in place with a screw knob from underneath. You can quickly jump from loading a 3.5" shell to a 3" shell by inserting the shell dies or 3" to 2.3/4" or 2.5" by using the appropriate die.
Supplied in a slide top storage case marked in the die sizes.
