Some people seem to be disturbed by the fact that ABs might not exit the animal. The reason is the outstanding expansion of the bullet, which leads to a devastating wound channel.
The only one that I have ever used, failed to exit an antelope at 300 yards. The 140-grainer was launched at 3160 fps from a 7 mag. The shot was right behind the front leg. The bullet came to rest, perfectly mushroomed, under the hide on the opposite side after passing through the elbow.
I will take that performance any day.
Both my wound channels were very poor...
You'd think the 280AI would give them enough velocity to expand good at 550-odd yards....but I guess they can be pretty tough at that distance. There's that velocity window again.
I really think that's the reason we get people posting so many different results; starting and impact velocities are all over the map and no two shots are the same.
Vapodog: Maybe I am spoiled.
I have had so many fast kills from bullets that both stayed inside (and exited) that I don't give it much thought.
The buck hit with the 140 AB( pictured above )was the heaviest mule deer I ever killed; he staggered 20-30 ft, blowing blood out his mouth the whole way.
The other two bullets are 140 Bitterroots from a 280 and a 7 RM at 3100-3200 fps,and killed black bear and mule deer. Death was instantaneous in both cases. Without a doubt the BBC is the fastest killing bullet I have ever used within 300-350 yards or so.
Just a small sampling.
