I just started to try a 3 ball load but without success SO FAR. I'm using 3 X 50 cal muzzle loading balls (.490") seated in a wad. The major problem, as I see, is to get an INNER sabot to hold the 3 balls in line. I've only tried a paper wrapped tube (to fill the void in the wad left by using an undersize ball) but that won't work as the release of the balls isn't consistent. I have a couple of ideas but need some time to try them out. The reason I'd like to try this is to provide a better method of using Buck Shot for the short range/heavy bush and just to see if the concept would work.
