Deer: small/medium whitetail 1200 ft lbs
Large whitetail/mule deer 1500 ft lbs

Elk: 2000 ft lbs

For deer, I shoot a 270. 130/140 grain light magnum which has almost 1700 ft lbs at 400 yards.

For elk, I use a 7mm rem mag shooting 175 gr nosler partition (handloaded to 2900 fps) which has 1900 ft lbs at 400 yards. Max range about 300-350 yards.
