Reminds me of a video a guy did comparing a bunch of .308 rifles. Almost all of them performed well with one or two factory loads. Which one did well with all of them? Yep, Savage (I don't remember the model). Shot less than 1" with four different brands, all with different weight bullets. One group looked like the one above.

CFJ has experience like mine with the expensive bullets while the SMK's and Hornady ELD's are more tolerant of jump, the Bergers and 6mm Vapor Trail I have tried like to be jammed into the lands a bit.
