I'm possibly missing something, but it doesn't appear to be much of a statistically valid test. Four different calibers (including the .338RUM - who would expect that to match a .270 or a .308?) and no attempt to deal with manufacturers' tolerances or the known tendency of rifles to prefer some manufacturers' ammo over others. Plus, no description of how the rifles were rested or whether called flyers were included or excluded. It's a lot more a "I shot all these rifles and I [underline the I] got the best result with this one this time [underline the this time]."
Reminds me why the only articles I read in the gun rags are about historical items.
