DaveP- Too funny!
But seriously, if you got together with all the shooters who claim to shoot 1/2 MOA and then selected a group of shooters from them who actually do shoot 1/2 MOA consistently, there would be a lot fewer in the group. As one acquaintance of mine said, if your group opens up, you just shoot another group until you get a 1/2" group. Right? Or you shoot 10 shots and pick the best 5.
Shooting groups is as much a discipline as any kind of shooting. If you can't consistently shoot a 1/2" group, you need to practice. Or buy a better rifle. Or a better scope. Or better ammo. This is how you get the guys with $5,000 rifles with $4,000 scopes on top of them. If you don't have the skill, chase it with money.
