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.
mod 55s is in .177 calibre and mod 60s is in .22 calibre apart from this they are the same rifle, it is also available in .25 calibre but not sure of the model number.

assuming you are talking calibers and not models the difference between a .270 caliber and a .280 caliber rifle is .1 inches in combustion chamber diameter.both cartridges are based on the 30-06 goverment case.The .270 winchester is necked down and accepts a bullet of .277in.diameter.The 280 remington cartridge is also necked down from the 30-06 goverment case and fires a bullet diameter of .284in. The basic differencebetween both cartridges amounts to the bullet diameter difference of .007in.In other words both cartridges are essentially the same.
This all depends on the calibre of said rifle make and model :)
