I started with 20 ga over shot cards, but they moved around a bit. Switched to the 16 ga over shot card and got a nice snug fit, that wasn't too hard to insert. The reason for this method was it allowed me to make a 2 1/2" shell without changing or adapting my Mec grabber reloader in any way. I kept the pressures low, made myself feel good I was shooting a 2 1/2" shell, and seemed to get good performance. It is Hartin, thank you. I have since found a relatively easy way to cut the shell, using a piece of pvc pipe as a guide.

This ain't a dress rehearsal , Don't Let the Old Man IN
