I saw this on another forum and it makes a lot of sense to me. I especially like the last point.
The newest cartridges share some or all of these traits:
Minimal case taper
30 degree shoulder angle
Longer or shorter parent case of a much older cartridge
Faster twist rate compared to older cartridges of the same bore diameter
Designed to use heavy for caliber bullets
Closer tolerances on cartridge dimensions and leade angles than older cartridges of the same caliber
Rifles with the new cartridge in retail stores ahead of ammunition choices from more than one manufacturer and brass for handloaders
Designed in a standard line and an ultra light version
Marginal external ballistic improvement over older cartridges.
Later in the thread the comparison was made with a 300 H&H and a 300 PRC. Inside of 400 yards there is little difference in the external ballistics of the cartridges with 150 and 180 grain bullets. Forget about what is considered long distance hunting and what is not. I think the vast majority of hunters will not go beyond 300 yards on a good presentation of a big game animal.
