Thanks for all the info, though I had heard of the blog before, and even looked at it more than once. Had even heard of using a shotgun that fits in the field.
I have found, however, that there are ways to test scopes without having the 25-yard setup, including (but not limited to) mounting them on a rifle and shooting. In fact, I've found shooting often provides more information, since not all scopes take kindly to actual shooting, including some expensive ones.
Have also known quite a few people who somehow consistently hit animals beyond 500 yards without big variables. Some even use 6x, but more than one prefers a fixed 10x.
Gotten your pair of variables back from the repair shop yet?
