I either carry Speer Gold Dot or Federal HST, both 230 gr.
The Gold Dot is a tougher round as the lead is more bonded to the jacket. You won't get as much expansion out of them, but they'll go thru just about anything.
Talked with a Federal Rep. last week. He says the only reason they still sell Hydra-Shok, is because folks are still buying it. They haven't improved the bullet in many years. They have had much problems with inconsistent feeding and expansion.
Here's a pic of a Fed HST that went thru a windshield, and took out a perp, center mass.
Here's a pic of a Gold Dot that went thru a wall, which would be two thicknesses of sheetrock, and came to rest inside the body cavity.
Here's an HST round, before and after being shot into ballistic gelatin. It averages over an inch of expansion every time, with an average of 12+ inches of penetration.
