According to Lucky Gunner, 147gr HST has a decent chance of over penetrating?

http://ift.tt/2mkUhE4 lot of people recommends HST or Speer Gold because they are proven to work. I kinda just went off my peers in getting my defense ammo: 147 gr HST +P. Bought a few hundred rounds and have been carrying it ever since.I just stumbled across lucky gunner's ballistics tests of multiple defense ammo and it looks 147 HST +P is barely staying within the 12"-18" requirements, with 2 out of 5 shots actually over penetrating.Is this a cause for concern? Do I need to switch carry ammo now?What are your thoughts on this? via /r/CCW http://ift.tt/2n2vyIZ
