Squeeze and individual pellet with a pliers, lead will flatten easily Bismuth will flatten a little harder and will crack and tungsten/steel shot won't flatten. I stopped at Bucksrun in MN a few years ago to pick up some Nice Shot and was told they wouldn't be messing with it as there was so little interest.. I don't believe RST is loading it any longer or have I heard of another source.

After the first shot the rest are just noise.
