These new "High Velocity" loadings offered a nearly 300 ft/s (91 m/s) increase in velocity over the original 1,050 ft/s (320 m/s) .22 LR load. [ citation needed ] This increase in power of the smaller round, coupled with its cheaper price and sheer number of rifles already owned in .22 LR, effectively killed the .22 WRF.
The CCI Stinger was the first hyper-velocity .22 LR cartridge and provided a significant increase in velocity and energy over standard rimfire rounds. The Stinger case is slightly longer at .702 in (17.8 mm) versus .613 in (15.6 mm) for the long rifle case, but the plated hollow point bullet is lighter and shorter at 32 gr (2.1 g), giving the ...

It is currently the fastest production .22 caliber round in the world with muzzle velocities as high as 4,600 feet per second (1,402 meters per second). However, the .220 Swift still holds the record as the fastest .22 caliber centerfire cartridge with a published velocity of 4,665 ft/s (1,422 m/s) using a 29-grain (1.9 g) projectile and 42 ...
The standard velocity .22 short launches a 29-grain (1.9 g) bullet at 1,045 feet per second (319 m/s) with 70 ft·lbf (95 J) of energy from a 22 in (559 mm) rifle barrel and can penetrate 2 inches (51 mm) of soft pine. [1] As a hunting round, the high velocity hollow point Short is useful only for small game such as tree squirrels and rabbits.
