What is "way more power"? Can you describe what that means and how it relates?
Reduced 7mm-08 ammo shooting a 140gr bullet at 2365fps will have 1738 ft. lbs. and a Taylor KO factor of 13,
120gr bullet @ 2675fps will have 1906 ft. lbs and a Taylor KO of 13.
A .223 shooting a 60gr bullet @ 3160fps will have 1330 ft. lbs. and a Taylor KO of 6.
I know many people regard these numbers as nothing more than numbers but many others regard them as a measure of the ability to cleanly kill an animal.
