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.
The 25-06 Remington takes its design from a marriage of the quarter-inch bore and Charles Newton’s .30-60 Springfield cartridge. This necked-down version of the .30-60 has existed as a wildcat cartridge since its inception around 1920, introduced by the A. O. Nidner. The cartridge came at a time when the conditions encouraged independent gunmen to experiment with it. This, and the release of the IMR 4350 in 1940, which greatly improved the performance of the .25-06 case, increased the popularity of the wild-cat cartridge. Thus, the natural occurrence was its commercialization which occurred in the late 1960s by the Remington Arms company.
A factory load of 100 to 117 grains can be easily propelled at a muzzle velocity of 3200 fps, generating energy levels up to 2500 ft-lbs. The .25-06 is a flat-shooter that is effective over 350 yards (with nothing more than a 5-inch difference above or below your aiming point) as well as 50 yards. The flatness minimizes range-estimation errors and provides quality shot placement, making it a fine cartridge for hunting anything from coyotes to large deer.
Lighter weight bullets are used in this cartridge, giving it lower recoil than its counterpart, the .30-60, in a similar weight rifle. This kick is bearable, but shoot for a long time at a stretch and the recoil begins to turn unpleasant.
If you have got a bolt-action or a single-shot rifle, you will notice that most often than not it offers, as its standard chamber,.25-06. It still remains a top experimental cartridge, which can be hand loaded (or reloaded) to the users' satisfaction.
