Well Im bored at work and thought Id do a little bit of research and put some info up on a few of the more popular rifle cartiridges, most of the info came from wikipedia and it could be wrong but its more for people like me who dont know a hell of a lot about them. Cheers Freedom.

.22LR

The .22lr (long rifle) is the most common firearm sold in the world today. The name .22 comes from the projectile size which is .223 in, and comes in a variety of lengths and strengths, such as :

Subsonic, which also includes "target" or "match" loads, at nominal speeds below 1100 feet (335 m) per second.

Standard-velocity: 1120–1135 feet (340–345 meters) per second.

High-velocity: 1200–1310 feet (365–400 meters) per second.

Hyper-velocity, or Ultra-velocity: over 1400 feet (425 m) per second.

It is predominantly used for target shooting or small game such as possums and rabbits and is effective within approximately 150m, although practically this range will be much less.

.17 HMR

The .17 HMR ( Hornady Magnum Rimfire): is a rimfire rifle cartridge descended from the .22 Magnum. It was developed by necking down the .22 Magnum case to take a .17 caliber (4.5 mm) projectile. Commonly loaded with a 17 grain (1.1 g) bullet, it can deliver muzzle velocities in excess of 2550 ft/s (775 m/s).

Its much less common than a .22lr yet more expensive, however it can reach much further distances than the .22 making it ideal for long range small game.

.223 Rem

The .223 Remington is a sporting rifle with external dimensions very close to the 5.56x45mm NATO military cartridge. The .223 is excellent for longer range small game shooting with the capability to kill goats, deer and pigs. The .223 Remington was developed as an enlarged and higher velocity version of the .222 Remington, which was introduced in 1950 as a varmint cartridge. The .223 Remington was developed specifically for the Armalite AR-15, a version of which later became the U.S. military's M16 rifle.

.243 Win

The .243 Winchester is a very popular sporting rifle round. It is ideal on game such as deer, goats and pigs and also for long range small game like the .223 Remington. It uses what is basically a .308 cartridge case necked-down to accept a .244 in/6 mm bullet. The .243 is well known for its accuracy, very flat trajectory, and relatively mild recoil compared to other cartridges.

.270

The .270 Winchester was developed by Winchester Repeating Arms Company in 1923 and unveiled in 1925 as a chambering for their bolt action Model 54[2]. The cartridge is based upon the .30-06 Springfield, and the case is slightly longer due to the necking down process. It is a very popular big game rifle through NZ expecially in the South Island for longer range shooting. Driving a 130-grain (8.4 g) bullet at approximately 3140 ft/s (957 m/s), the .270 offers superb accuracy in good bolt action rifles, an extremely flat trajectory, and good long range punch, all at a level of recoil tolerable to most shooters.

.308

The .308 Winchester is the commercial version of the military 7.62x51mm NATO centerfire cartridge. It is also commonly used for civilian target shooting, military sniping, and police sharpshooting. The relatively short case makes the .308 Winchester especially well adapted for short action rifles and the it could be considered the most popular short-action big-game cartridge among hunters worldwide.

The .577 contains a .585 inch diameter 750-grain (49 g) Monolithic Solid Projectile which when fired moves at 2,460 ft/s (750 m/s) producing 10,180 foot-pounds force (13,800 J) of energy.[1]
