I have the same gun, and I also use it for cowboy action shooting. I feel the same way; it's not for sale!
My cowboy action load is a 200 grain RNFP over 4.2 grains of Clays. I have a 255 grain RNFP mould to use for heavier shooting, but for folks who don't shoot cowboy action, keep in mind the name of the game is whacking steel plates at close distances as fast as you can. Light loads rule the day, but the gun will handle powerful loads, too.
