I'm another supporter of RST. In my 2.5" 16 bore (gun built 1866, damascus barrels probably 1872 or earlier) I only shoot my reloads that have been tested by Tom Armbrust or RST.

The last shells I ordered from RST were ordered by phone on a Monday and delivered that Thursday for $8 shipping. Not only is Morris a good guy but Alex also. Both are big supporters of our double shotgun sports.
