If you apply as many of the goals and needs across both target and hunting in a list...you'd find these 21st century 6.5's have a 21st century level versatility and efficiency to hit more, most, if not all, the check boxes in the most diverse listing you can come up with.
For specialist like yourself who does custom guns, reloading etc. It's pretty meaningless. But try to imagine how big the list is for all shooters/hunters target/hunting and their needs/wants and you start to see why. Off the shelf means anyone, off the shelf can compete target or game, 41 grains of powder and 140gr pills means pretty much everyone on recoil standpoint and still shoot well (kids/family etc.), cost, availability, goes on and on.
You do so much more with less when you have 21st century ballistics/bullets/cartridges/rifles. Versatility Max. Run impact velocity, wind drift, drops etc. of a 6.5 creed against a bunch of 20th century options and you come to see it mirrors a 300 wm running a fairly heavy modern bullet. More than half the shooters won't shoot one of those options very well. Run a 6.5 Grendel against a bunch of others you you find a 3/4 scale 308 running 168's is the mirror with 55% less recoil, or run it against a .243 moot to 300 but the higher bc bullet walks away from factory .243 after 300 yards. A 6.5 PRC runs impact velocities/drifts/drops with a 338 lapua....can't imagine that recoil difference. And you can do this all off the shelf with these three 6.5's. Wouldn't have imagined we'd see this level of versatility and capability off the shelf even 20 years ago.
We've come a long ways from 'throw a 180 out of a 30 cal and your gtg' days. I mean that still works but so not necessary, you can increase your versatility 10 fold with a modern 6.5 and reloading/custom stuff has now become optional.
