Triple 7 likes the case full, but not compressed. I've loaded a lot for my '66 carbine, in .45, but I really don't like those loads in a SAA. They're pretty hot, I'm not sure I would recommend them for an open top. I use Schofield brass when I load for my pistol, I have used 777 or Goex both for that. I've never used wads, or filler with 777, and I can't remember what the manufacturers recommendations are for that.
