gleason.chapmanI also have heard many things about the SW, my personal experance and that of the other guys in the club here indicat that they work quite well as long the velocity is up over 1900 fp. I am inclined to believe that they are designed for the upper end of a muzzleloader velocity range and that the people that have had a problem with them were using less than 110 gr of 777 or 125gr of Pyrodex[ just my opinion] I use the 200gr and the 250 extensively in my Omega for the last 3 years and have had excellant results.
