Cookieman,
I talked to Steve Hornady a few months ago about them making the 20ga SST, he said it is in the works and will be available in the fall of 2006. These are lighter and slower than the Rem and Win offerings so may not have quite as much FPE but should be a better BC. The 20ga SST is 250 gr vs 260 gr in the Rem & Win, and the 12 ga SST is 300 gr vs 385-400 gr in the Rem & Win. Can't wait to shoot some myself.
