Some reports have it being a bit "hotter" than domestic stuff, causing issues with extraction in some Marlins. At least, that's what they say over on Marlinowners.com
I haven't tried it yet, but other posters over there say all it takes is keeping the chamber spotless to overcome the extraction issues.
I've got plenty of WW stuff that my 336SC likes, so I'm set for quite awhile.
BTW, it's sold at Academy under another name, Monarch, I think, so you might keep an eye out for it there, too.
