Quick double check confirms, air resistance (drag) slows the bullet with a force proportional to the square of the velocity. Basically for every little increase in velocity you get a lot more drag. Also the concept of bullet velocity as being so important came from a time of poor BC bullets and no practical ability to adjust for environmental conditions and range estimation. You needed a flatter shooting rifle to compensate for errors. Now a 180 grain 7mm Berger with a G7 BC of .340 at 2800 fps has plenty of energy to kill a bull elk beyond 600+ yards plus rangefinders and ballistic compensation eliminate the need for speed. This new cartridge was designed to titillate gun influencers and their followers. Not hunters.

Another 30 super carry unless I miss my guess.

Those thin jacketed bullets are not the answer to killing.
