I have shot a total of 5-6 140 AB's into 3-4 decent sized deer and recovered the very first one today.
Bad shot on my part, quartering away hard(150-200 yards?), hurried, dropped him on the spot but required a broadside finisher 100 yards later(textbook dime in, golf ball out through a rib and little shoulder).
I wouldn't take a first shot like that unless I had confidence in the bullet.
The 140 Accubond in 270 is uber.
Found on the offside hide after ruining a bunch of good vension. Missed the mark by about 3" left.
