The .22 Winchester Magnum Rimfire, also known as the .22 WMR, .22 Magnum, .22 WMRF, .22 MRF, [2] or .22 Mag, is a rimfire cartridge.Originally loaded with a bullet weight of 40 grains (2.6 g) delivering velocities in the 2,000 feet per second (610 m/s) range from a rifle barrel, .22 WMR is now loaded with bullet weights ranging from 50 grains (3.2 g) at 1,530 feet per second (470 m/s) to 30 ...
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 .22 TCM (Tuason, Craig, Micromagnum) is a proprietary bottlenecked rimless cartridge derived from a 5.56×45mm NATO (.223 Remington) parent case. It was developed by custom gunsmith Fred Craig in collaboration with Martin Tuason, the President of Rock Island Armory (RIA) and Armscor.
The rimmed .375 H&H Flanged Magnum for double-guns and the .375 H&H Belted Rimless Magnum with a headspacing belt for magazine-fed rifles were released simultaneously in 1912. .375 Ruger: 2007 US 1 [4] R [5] 9.5×65.5mm 2840 [4] 4835 [4] 3.405 90.5 [10] 0.375 [10] 0.430 [5] 65.5mm Developed in collaboration between Ruger and Hornady.

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 ...
The .22 Hornet or 5.6×36mmR Hornet [2] is a varminting, small-game hunting, survival and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than the rimfire.22 WMR and the .17 HMR, achieving higher velocity with a bullet twice the weight of the .17 HMR bullet.
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 ...
Also the muzzle energy is only an upper limit for how much energy is transmitted to the target, and the effects of a ballistic trauma depend on several other factors as well. There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 ...
