Someone that doesn't roll their own will forever be at the mercy of marketing trends, as well as flaky supply chains and panics like several we've been through since 2008 or so.
I've had a 7-08 or two since the 80's. Maybe the best deer/antelope load ever.
The only way it will ever "go away" is when, if, the .308 is banned for civilian sales, i.e., never.
