I can't exactly call that much of a testing. HSM ammo is absolute crap. I understand that 338 ammo doesn't have a plethora of commercial offerings, but HSM should never be considered.
With a 1:9 twist, I have no idea why they tested heavy bullets. I'd have used 180-225gr, and likely cut those groups in half.
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
Why do you feel it necessary to list your guns?
