Anyone have any experience using this in 158-grain LSWCHP in a J-frame? They make some pretty strong claims for it--+P velocity from a two-inch barrel, lower pressure and recoil, very soft lead for more reliable expansion, and minimal flash. They say they achieve these remarkable results with advanced powder formulation, as I understand it.

I shoot the old FBI +P load in my EDC, but this stuff sounds fairly impressive if the claims and figures are accurate.
