Reams have been written about 270 vs. 30-06, then the LRF becomes ubiquitous, optics manufacturers start installing "holdover" reticles and 50yrs worth of Gunwriting, bar-room/coffee-shop arguments become moot because every bottleneck "deer" cartridge has a similar enough trajectory so as to be able to all use the same holdover scope.
Now we're comparing/contrasting minuscule differences at ranges so far that damned few could actually quantify the difference on paper to the difference on a target off of a bench. A whole bunch fewer could discern the difference shooting from field positions.
There's not a single new "hunting" cartridge "developed" within the last 20yrs that's capable of doing something that wasn't already being done either by some other factory offering. There is no new Cartridge/Caliber, rifle, or optic that's going to suddenly make you a competent 500yd+ shooter. Lots of time and ammo expended shooting @ 500+yds makes you a competent 500+yd shooter.
