I also use W296 (22 grs as I recall) under a 240 gr Hornady XTP. This load shoots well out of my S&W 29 and my Rossi Puma rifle. Its a bit stout and unpleasant to shoot however in my Taurus Tracker even with the porting.
But on game (deer) its devastating. I've shot 4 deer with this load and I don't recall any of them taking a single step. But these were all 50 yards and closer.
