That's fair enough, but the problems he states with the 6.5 creedmoor are isolated incidents, not an epidemic problem with the cartridge/chambering. It's presented as a grand conspiracy that Hornady is putting out a bunch of hype and delivering a sub-par product with fundamental issues. If I had to take a guess, PTG cut him an out of spec reamer and that's the source of most of the problems.
Headspace dimensions on the SAAMI print call out a .007" tolerance so his claim of .007" variance don't necessarily mean anything is out of spec-- if anything accounts for a single lot of cases. He claims to know about the machines that make cases but also claims that Hornady isn't making their own cases because the anneal was or was not acid washed off. You simply can't make bottleneck cases without annealing the brass between draws/sizing operations. You can see this same change between batches of 6.5 SAUM brass... Doesn't mean there's a conspiracy of manufacturer.
In total agreement here with you. With the entry of other brass manufacturers like Lapua and Peterson the brass is a non issue.
A huge aspect that Randy misses with the Creedmoors and PRC's is the fact that SAAMI spec chambers are geared for both accuracy and functionality. You get increased accuracy in factory production rifles and ammunition-- for most of is we don't care because we can get a reamer made to whatever spec (throat/neck and/or body geometry) we want, but it does advance the capability of those on a budget or those who don't want to go the custom route and that's important to keep in mind. So when he says a 300 Wby does the same thing a 300 PRC does.... IMO it's not the whole picture. Sure, the speeds are similar, but you can't seat ELD/VLD bullets at mag length in the Wby, and you can bet that the PRC chamber is going to lend itself more towards accuracy than the factory Wby chamber.
Can you get a custom 300 wby reamer made and achieve the same level of precision with a match barrel? Sure. But in the realm of buying factory rifles, where's the hype in a match-grade chamber by default and $45/box .300 magnum match/precision hunting ammo. Look at factory 300 wby ammo pricing......
There's also some other considerations that Randy overlooked in the way of efficient powder burn, case capacity fill, etc...
