There is also the possibility that there may not be an answer.
The IDPA Nationals one year had a BUG side match, snubby revolvers provided by S&W, .38 Special ammo by CorBon. The ammunition was their Performance Match with plated bullets, not their hollowpoint gunfighting stuff. The guns were hot and dirty and we were peppering the rather close targets with fragments of copper as the plating peeled off.
Plated bullets are not a good match for revolvers, sometimes they work, sometimes they don't.
