Go to the Corbon website and focus on the Glazer Safety slugs or Pow'r Ball loadings.
Admittedly I haven't read about any actual reports on BG's being blasted with a Pow'r Ball load in anything, but they look like they're guarenteed to expand -
rapidly!!!!
As for the Glazer Slugs, I've only read of ONE INSTANCE where a BG survived being shot with one. But he will spend the rest of his life with only one lung left in his chest.
Bet his criminal days are over!
