The 2 1/2" shells can be cut down 2 3/4" shells with either a band saw or a wooden dowel with a single edge razor stuck in it at a 20 degree angle the proper height up. If you're going to fold crimp you'll need a 1/4" spacer to go under the drop tube and crimp stations. You can make one or buy Mecs "short kit." If you're going to roll crimp then that won't be necessary but a tool from Precision Reloading or BPI will be necessary. The PRing one is better. In MHO the roll crimps look cool, but are a PITA for reloading after the first time. The shell stays rolled over a little and has to be straighten. When I roll crimp it's shot and toss.
