I bought a used 10g MEC Steelmaster from the LGS and fitted a homemade short kit using 1/2” plywood and a few washers. Works like a champ. I have one 10 with tight chambers and the resizing collet allows me to adjust resizing. My load is the tried and true 19 grs of RD in hull of choice with a payload of 11/8 oz. Black powder loading on the MEC is easy, with a dipper used to dispense powder. From a friend I bought a short kit for my PW 375. I could never get it to crimp very well, which is why I use the MEC exclusively. Plus on the PW the resizing function is not adjustable. Short 10s are a hoot. I recently picked up a Parker 10 on a #2 frame. It’s probably a pound lighter than the usual Parker 10 on the standard #3 frame. Can’t wait to try it on doves.
