Yes, a very major difference. The .223 Remington was designed from the ground up as a varmint cartridge, with its origins in the .222 Remington and later the .222 Remington Magnum. The .270, on the other hand, is intended for larger game - it is essentially a .30-06 cartridge, necked down to accept a smaller projectile.
It's a matter of physics and basic ballistics. The .223 is at least half the weight at 55 grains and on most loadings is somewhat slower than the .270 cal. The .223 will have less penetration power at equal distance and more perceived drop, because it takes more time to reach the target. At close ranges, the difference will be minimal, but as the range opens, the differences become more apparent. Both will kill with proper aim, but the .270 is far more able to handle larger game with it's higher power and flatter tragectory.
The 270 is more powerful. The .270 has a slightly larger projectile in diameter (.277 vs. .224) and a significantly heavier bullet (between 90 and 150 grains, vs. 45 - 80 grains for .223/5.56 loads). Additionally, the .270 utilises a much larger casing - the .30-06 casing, necked down to accommodate the smaller projectile of the .270 cartridge.
Main one is bore diameter. Another answer: 270=.277 diameter 30-06=.308 diameter

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.
'Difference' is a mathmetical expression for subtraction. 7 #Hence 270 - 108 = 162 (The difference).
I believe they are the same

The difference is 270 degrees.
10 has short action, 110 has long action. Differerence is about 1 /4 inch in the length of the Receivers. Short action calibers include .223 up to .308, Long action calibers include 270, 30-06 and magnum calibers 7MM and up to 458 Magnum.
.270 WCF means Winchester Center fire. Yes, same round- and IMHO, one of the best rifle cartridges ever made.
