Hornady is doing what wildcatters/reloaders/tinkerers have been doing with cartridge design and that's what makes them so polarizing.
Factory ammo shooters love it, because they are designed correctly (twist rate, shoulder, neck length, bullet location with heavy bullets, throat length) so they work well,
Tinkerers get annoyed because then they are told their 7 mag throated for bergers is now redundant and they did the "hard work" themselves.
Anyone that's buying factory ammo for precision work and buys a 7mag over a 7prc is simply making a bad choice. 300 win there are some options, but now that the long berger 215 factory ammo is gone it's pretty evident the prc is better for that use case.
Same with 243 and 6 creed, all the ammo is hunting ammo with crap bc for lr, and most of the rifles are twisted for bullets shaped like bricks. 260 isn't even pretending to be alive anymore, for 6.5prc comps 6.5-284 ammo is produced what once a year? Buying a -284 and not reloading is… an interesting(bad) choice. You could get a 6.5-300 weatherby i guess if you want to waste money and never shoot it.
