CLARK; what is the meaning of the yardage on your list?
I take the muzzle velocity of a cartridge and use Quickload/Quicktarget to calculate how far that bullet would have to travel to slow down to the muzzle velocity of a lesser cartridge.
The 7mm-08 is 198 yards as it takes for the 162 gr plastic tip boat tail bullet to slow down from the 3158 fps of a 7mmSTW to the 2789 fps of the 7mm-08 muzzle velocity.
I like to play that game to show that the 22-250 has little over the 223 and the 17HMR has little over the 17M2.
