Of course, I'd pretty much forgotten why I asked in the first place.
Where C.O.L. can really mess up one's gray matter is when a company (let's say Remington) chambers their rifles (let's say a 700 PSS in .308 Winchester) with throats so long that the bullet won't seat with more than 1/10" in the case neck when it's close to engaging the rifling. Good, accuracy is wonderful! Then the damned rounds won't fit in the rifle's box magazine.
I gave up and just seated the darned things to fit in the box magazine. Accuracy is still pretty darned good, but that bullet jumps quite a ways!
