Here's a link to some decent testing of several 9mm defensive loads.
He tests my two primary carry loads, which are 115 gr. Federal 9BPLE and 124 gr. Federal HST. Both loads seem to have good results, and the 147 gr. HST's show some really impressive expansion. I would carry Speer Gold Dot's, but I can't justify the price difference over the 9BPLE or HST.
What 9mm defensive ammo do my readers use?
