I know that penetration is a combination of bullet construction, its sd, speed and many other factors but i found the 9.3 as one that really seems to punch through...Is there anything the 9.3 won't kill just as dead under 300 yds? A good friend shot a hog at 150 yds and killed the one behind it and exited as well (should have planned that better). Never had a 338 and don't feel the need but I suspect its the better choice over 300 yds....but that's not my territory.
