Reported Shooting Accuracy

It's been fun reading the various fora on firearms. There are always the folks who say that pistol X shoots "dime sized" groups at 25-50 yards with their .22 pistols. With the typical $200-400 semiautomatic, shooting good, but not the best ammunition, I seriously doubt that most of these guns will be that consistent. Freehand, I doubt there are very many people who can manage that. Being old, shakey and with failing eyes, I tend to measure my groups in fractions of barns, truck tires or 55-gallon barrels. Actually, on a good day, 1-2" is achievable. However, some of my targets look like I'm trying to emulate buckshot.

Oh, well, maybe they can really shoot that well. But if they are, why aren't they shooting the $1000 target pistols?
