I think a couple of things are involved. Many of the "independent" reviews, are not. Not that the testers are on anyone's payroll, but they depend on the makers for rifles to test. And small groups are always welcomed. I think the best reviews are those posted by owners on the various forums. In defense of short range testing, it will generally disclose any significant issue with the rifle's performance. I usually begin shooting at 25 yards. I don't believe I've ever shot a full power rifle that shot great at 25, but poorly at 50. If it's shooting tiny, one-hole groups at 25, then it's ready for more challenging shooting. Some of the testers conclude this, and go no farther. In contrast, if a rifle is shooting half-inch plus groups at 25, or with flyers, something is off, and I'll make change in pellet or tuning, or check the barrel, before continuing. But I agree, 20-25 yard testing should not be the final analysis in a precision rifle.
