This video compares Fiocchi Range Dynamics and CCI Standard Velocity .22LR ammunition at 100 yards using a CZ 457 rifle. While both ammunitions are 40-grain lead round nose, the Fiocchi exhibited significant inconsistency and flyers, resulting in a larger average group size (2.23 inches) and mean radius (.73 MOA). CCI Standard Velocity, despite also having flyers, demonstrated better overall consistency with a slightly smaller average group size (2.21 inches) and a tighter mean radius (.66 MOA), making it the preferred choice for accuracy in this specific rifle setup.
