I don't known of any evidence that indicates that those rounds are among the most popular.
Sure, they're on a list but I wouldn't call the 50th most popular, "popular". Are they top 10? I doubt it. Top 30? Who knows?
Since you define popularity "over time", those rounds (.30-06, .270, .30-30, etc) have remained popular for many decades. 357sig, .270WSM and 6,8spc haven't even existed long enough to meet your criteria.
If you start getting onto "popular" but only for 3 years, 5 years, or whatever, you then have to define what qualifies as "popular". I'd be willing to bet that most gun owners have never even heard of 6.8SPC.
There are lists put out by RCBS on the most popular dies, I've never seen any of those (except .270WSM) on the list, not in the top 25 anyway. I don't call that "popular".
