I wouldn't mess around with cardboard wads, .410 wads, or gas checks. These Speer capsules just plain work! The box they come in has loading data right on the outside.
I've loaded these in .357 and 44 mag. They're fun to shoot clays thrown in one hand while the revolver is in the other hand, meaning they're pretty close, not more than10-15 yds. I never tried to take game with them, it's illegal here in WI. , to use a centerfire handgun to shoot small game. As a survival item, I don't doubt they would work, I'd use nothing smaller than 7½ shot.
