I agree that Barnes X bullets are great penetrators and leave a pretty "ragged" wound channel if your rilfe has the velocity to open them up. One could run into a challenge if one is using X Bullets designed for a higher velocity rifle in a lower velocity rifle. -- say 500gr Barnes X designed for an impact speed of 2100-2600 fps in a 458WinMag or Lott or 460 and drop it into a 45-70 at say 1500fps then one is taking the bullet outside it's design specifications and it may or may not function as advertised. I noticed the "power" bullets Barnes promotes for the 45-70 don't look like the Barnes X bullets, even the pointed ones have lead showing (I assume to help them open up at 45-70 speeds).

Of course if one uses a non-spec Barnes X and they don't open up all, then one certainly has an sexy, attractive looking de facto solid. All loaded up, they would look pretty with a handful laying out along side a bulk plastic ammo box next to a Ruger No. 1 at the bench rest station. I'm sure it would make for some conversation and like with Garrett, some great penetration if that is the sole and entire name of the game.

Good Luck and Good Hunting,
