SSK will I'm sure. They make a few wildcats based on a full length .444Marlin then necked to size. I have a .411JDJ in a 12 inch Mag-Na- Ported SS Contender which is just such a wildcat. BTY it is for sale if you are looking, comes with dies, formed brass, and a bunch of bullets. I have everything covered with my other .41s'. The .411JDJ is becoming a safe queen.
