Is a 223 rifle bigger in caliber than 243 rifle?

No. The .243 is a larger calibre, and the parent case is the .308 Winchester, necked down to accept the smaller projectile. It's considerably more powerful than the .223.


Which is more powerful a 223 calibre rifle or a 22 calibre rifle?

It depends. A '.22' rifle, if you mean centrefire, includes alot of calibres as the term is generally used to mean any ammunition loaded with a .224 calibre bullet.Such calibres include .222 Rem, .223 rem, .22-250, .22BR, .22 Dasher and plenty of others.Of these, the .22-250 is by far the most powerful. It is essentially a .250 Savage case necked down to take a .224 bullet and so holds alot more powder than any other '.22' round.In terms of foot pounds of energy, a .223 Remington will generally produce about 1,200 FPE whilst the .22-250 will produce about 1,750 FPE.************However, if by "22 rifle" you are referring to the RIMFIRE .22, such as .22 LR, the .223 is much more powerful.

What is the difference between 222 and 223 calibre rifle cartridges?

The .222 Remington was the parent case for the 5.56x45/.223 Remington cartridge, and it was also the parent case of the .222 Remington Magnum (which was rejected by the military prior to the adoption of the 5.56x45). The .223 has a longer casing, which holds more powder, as well as differences in neck and shoulder measurements. The two cartridges are NOT interchangeable.


What is the best all round Hunting Rifle Calibre small to medium game in Australia?

It depends on what you wanna hunt mate. I've got a .223, .243, .300, and .375H&H, as well as a .22 and shotty. A .223 is the best calibre in my opinion if you arent looking for buffalo or bulls.
