I've not found a spreader in 20 ga. that I could recommend, buzz. If you had asked about a 12 I would say the Fiocchi Interceptor unhesitatingly. But alas, they do not list them in any other gauge.
RST has 20 ga. spreaders but at $16 a box I'd have to look long and hard elsewhere before ordering them. If I were to try reloading some I'd start with this wad from Ballistic Products. It is very similar to the wad in the Fiocchi 12 ga. spreaders I use so much for sporting. Has the X post in the center. In fact, I may order a bag and load some up just to see. I could use some good 20 ga. spreaders, too.
Good luck, SRH
