220 Swift Ammo
The 220 Swift Ammo remains the fastest production cartridge ever made. It dates back to 1935 when Winchester introduced it into their model 54 bolt action rifle. The original inspiration of the 220 Swift Ammo came from Grosvenor Wotkyns, who wanted to neck down the 250-3000 Savage case. However, Winchester necked it down to .22 caliber and loaded it with a 48-grain bullet with a muzzle velocity of 4110 fps.
The 220 Swift Ammo uses .224 bullets despite its name and continues to be the most accurate high-power .22 cartridge created. Like other high-velocity cartridges, it usually has erratic performance on larger specimens unless you utilize bullets constructed for this purpose. The .220 Swift Ammo shoots flatter than other ammo at 325 yards. It is also known to deliver 725 foot-pounds energy.
The cartridge length of the 220 Swift Ammo is 2.680 inches, leaving enough room for standard short-action magazines. In addition, with its powder capacity, today’s longer high B.C. bullets are an excellent choice for increasing its versatility. With the 220 Swift Ammo, you can achieve muzzle velocities as high as 3,350 fps with a 75-grain bullet.
It is also famous for its precisions and offers users long-range performance and minimal wind deflection. Besides its use for long-range rodent control work, it is also ideal as a long-range coyote cartridge. In states where .22 calibers are legal for hunting big games, the 220 Swift Ammo is a proven killer of mule deer, pronghorn, and even whitetails. It is an excellent choice for ringing steel at a distance; all you have to do is pace yourself.
The development of the 243 Winchester Ammo is partly owed to the famous gun writer Warren Page. It is based on the 7.62x51 military case, which was necked down to .242. The reason behind its creation is that hunters would have access to ammo that would perform well on predator/varmints and deer-sized games. The .243 Winchester Ammo delivered excellently on this expectations.
When you use 90 and 100-grain bullets, it will handle deer and pronghorn antelope easily. However, the lighter bullets work excellently with foxes, woodchucks, and many more like them. In addition, it offers a light recoil, ensuring that shooters can accurately place their shots. This is possible irrespective of their recoil sensitivity. This balance between versatility and light recoil is why it is one of the most famous rifle chamberings in the world.
The .243 Winchester Special is being chambered in the Model 70 and the Model 88 lever action. Both offer accurate shots and ensure varmint hunters enjoy precise shot placements. Additionally, its best virtue is the killing power it provides for medium games. It provides the killing power at a noise and recoil level that helps hunters shoot calmly and accurately. In addition, it has enough power to penetrate a medium-sized deer's shoulder without exiting the broadside.
The .243 Winchester Special is ideal for games weighing 80kg because it cannot ensure sufficient penetration on larger games. Although it will cause free bleeding, the killing will be slow, allowing animals to run considerable distances. The fastest kills are achieved within 200 yards and at impact velocities between 2650 fps and above.
