The 17 Aguila is a newer cartridge introduced into the market during 2004 and is based off shortening down the .22 long rifle cartridges. The bullet diameter is .172" but fits on the shell casing due to its modified reduction of the neck. The cartridge was developed in conjunction by firearm manufacturer High Standard and ammunition manufacturer Aguila in 2003.
The 17 Aguila is a varmint round designed to have less expansion on entry to do less damage to the tissue of an animal. The bullet is a 20gr jacketed solid point round that travels at 1,850 ft/s. This allows for game hunters to salvage more edible meat off a carcass. The bullet is designed to fit into a .17 Mach II (17HM2) bolt action rifle with no modifications to the rifle, or changing out the barrel on a Ruger 10/ 22.
The bullet received little attention on the market due to two other rim fires that were also released into the market by manufacturer Hornady. The .17 Hornady gained traction and took over the market in rim fire casings after their release. The 17 Aguila did gain a following after varmint hunters noticed it had less expansion that allowed for more edible meat to be salvaged on game, while still staying accurate for well-placed shots.
303 British Ammo
The 303 British Ammo is so named because it was the standard British and Commonwealth cartridge from 1889 until the 1950s for their rifles and machine guns. It is more commonly known as the .303 and was invented by James Paris Lee. It has its origin in the United Kingdom though it was first developed in Britain as a black powder round before undergoing adaptation in 1891. The .303 British Ammo has since been produced and stayed in service from 1889 up until the present. It served in world war I, II, the Irish war, and the Greek war, amongst a host of others.
The .303 British Ammo is one of the few rimmed bottlenecked centerfire rifle ammo still in use today. It has a bullet diameter of 7.92mm, a neck of 8.64mm, a shoulder diameter of 10.19mm, and a base diameter of 11.68mm. Its rim diameter is 13.72mm, and it has a rim thickness of 1.63mm, closing off with an overall length of 78.11mm.
Due to its fast twist rate, the .303 British Ammo fires long and heavy bullets with a high sectional density. It also possesses an excellent penetrating ability. It is suitable for all medium-sized games and an excellent choice for hunting whitetail deer and black bears. The .303 British Ammo has a large rifle primer type with a muzzle velocity of 844m/s when fired with a bullet mass of 10g. It assures a sure shot kill in a range of at least 500m.
