He used custom hand loads for lots of rifles in the test. Possibly another flaw, but it is what it is.
I thought his conclusions were: more expensive does not equal more accurate but less recoil does.
Not a conclusion but a point of emphasis was that 20 round groups gave better data and looking at how many shots /20 fit in 1moa was better way to look at a rifles accuracy than 3 or 5 shot groups.
I think he picked a "winner" in five categories or so, but he was not trying to say buy a tikka or a bergara or a sig. It was just an example of how we should be looking at rifle accuracy data. People can then apply that to their own rifles to make choices about the guns in their own safe.
So yeah, he has an accurate tikka, but I don't think he was trying to say people should buy tikkas. He was trying to say, this is how you should evaluate accuracy. Again, not a conclusion but a main point.
Just my opinion, maybe I'm the one that missed the point.
