The .22-250 Remington / 5.7x48mm is a very high-velocity, short action, .22 caliber rifle cartridge primarily used for varmint hunting and small game hunting. It is capable of reaching over 4,000 feet per second. Some jurisdictions prohibit the use of cartridges smaller than 6 mm (e.g., .243 Winchester) for deer hunting.
Typical varmint rifle cartridges on a 0.25-inch (6 mm) grid (from left to right): .22 long rifle for very small animals at ranges less than 100 meters, .22-250 represents the high velocity .22 calibers for longer range shooting, and .25-06 for larger animals at ranges up to 400 meters.
The BFQ was first applied by Wroe et al. (2005) in a paper comparing bite forces, body masses and prey size in a range of living and extinct mammalian carnivores, later expanded on by Christiansen & Wroe (2007). [2] Results showed that predators that take relatively large prey have large bite forces for their size, i.e., once adjusted for ...
Cowboy mounted shooting (also called western mounted shooting and mounted shooting) is a competitive equestrian sport involving the riding of a horse to negotiate a shooting pattern. Depending on sponsoring organizations, it can be based on the historical reenactment of historic shooting events held at Wild West shows in the late 19th century.
Changing the diameter of the case (to suit a new caliber). Called "necking up" or "necking down", this is the most common way of making a wildcat. The new caliber allows a different range of bullet weights, and can greatly increase the velocity or the power or the resistance to wind drift as compared to the parent cartridge. Necking back.
Reloading dies for the round are readily available. The .225 Winchester's case is a parent case for some of SSK Industries ' [ 3 ] popular line of JDJ cartridges designed by J.D. Jones , chosen for its strength and semi-rimmed design which makes it well suited for use in break-open actions.
The prototype for the .220 Swift was developed in 1934–35 by Grosvenor Wotkyns who necked down the .250-3000 Savage as a means of achieving very high velocities. However the final commercial version developed by Winchester is based on the 6mm Lee Navy cartridge necked down, but besides inheriting headspacing on its rim from the parent, a feature already considered obsolete by 1930s, 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 ...
