308 Winchester 165gr triple shock x bullet
JBM ballistics sight 200 meters. 2371 ft-per seconds with 2060 ft-lbs energy,,, that's 1300 ft-lbs difference in energy
500 meters. 1750 ft-per seconds 1122 ft-lbs energy.
So that blows your math out of the water.
Guess your math isn't working for you SC.
The 308 has 64 more ft-lbs at 500 meters then the Grendal has at 200 meters.
Strange that you post this with out adding up the numbers.

There are some that feel ft/lbs are important. I didn’t include it because it, and momentum, are useless figures in determining the penetration ability of one bullet vs another.
