Gunwriters are shills for the industry. Industry wants to sell the latest and greatest. You can really pump something based on KE because KE is Mass times Velocity squared. Just increase the velocity by 10 and KE increases by 100.
It is a lot harder to increase the Momentum of something by ten. Momentum being mass times velocity.
By the way, only momentum is conserved, KE is not.
For decades gunwriters have filled canyons full paper on the difference between a 270 and 308, (about .031" ) KE spreads the shilling distance out to a respectable level.
Hey, who needs to aim, if you have enough velocity you can down big game regardless of where you hit them.
Don't worry, it is a Weatherby!
