.22LR Ammunition Testing (AccurateShooter.com)

In all precision shooting, one can only shoot as well as the cartridge will permit, which is why it is important to know approximately what the smallest grouping obtainable from each brand of cartridge is. The researchers compared the diameter of five five-shot groupings (for a total of twenty-five shots) from a .22LR Swiss-made Bleiker. 

None of this extensive research is mine, I simply consolidated and slightly modified it. To see groupings at 75 yards and the entire list, see the Original Author's website (AccurateShooter.com).
