I've seen posts about this test raving about it...people changing their minds on scope purchases etc because of it. Frankly this test in my opinion is flawed! The guy is not comparing apples to apples! The scopes he is comparing are different in so many ways! It is in my opinion invalid because of it! If he wants to do tests and be proclaimed an expert compare apples to apples...adjustments being equal, objective lens being equal etc...
The test or comparison is of the scopes that are primarily used in the prs series. Adjustments should not matter one bit provided they are accurate. Glass is glass some manufacturer choose large objective where others don't. The main thing is these scopes are all in the $1600 plus zone so they should be comparable to a certain degree.
