Here's a chart I put together quick to show the different energy output from different Barnes bullets. The bullet info I got straight from Barnes webstie, the velocity info I took from Blackhorn 209's website (Based on the correct bullets). I plugged the values in to an app called Strelok on my Droid. Pretty interesting to see how the heavier bullets really retain there velocity and thus their energy. The bullet drop is assuming a 100 yard zero. The values may and will vary based on gun, but it's still pretty neat to see the comparison.
