Rich, I don't know if they make die sets for 2 1/2 inch shells. The shell holder dies and the top die would have to be modified. Best to call them and ask. As I get more used to changing gauges, it will take about 10 minutes. The nice thing is, the shells look just the same as when you took the dies off the last time, no adjustments needed.

I’m not well acquainted with Spolars , I am however to a degree with PW’s . I might be wrong but they look very very similar . With that being said the people at PW told me they could make a PW LS-1000 10 gauge into 2 7/8” pretty easily . I believe if memory serves they also said the same about PW 800 Plus for the 12-16-20 . SO I would assume the Spolar may very well be as easily made for the shorter shells as well . Although this is just assumption on my part .
