Either can depending on the load
it all depends on your style of rifle more than anything. If you want stopping power the edge goes to the 308 but only slightly. a 270 will shoot more accurately at a longer range though.( by that i mean over 600 yards!) for me i think the 270 is better
It all depends on what you are hunting.
The parent case of the .270 is the .30-06, necked down. The parent case of the .243 is the .308 Winchester, necked down. Aside from the larger diameter of the .270, the .270 has a longer case.
Main one is bore diameter. Another answer: 270=.277 diameter 30-06=.308 diameter
308 is better it is a higher caliber and shoots farther unless you want a cheap gun 308s are more expensive making you want to choose a sucky brand 308 which makes the 270 better.
General rule of thumb is that the best caliber is the one which best suits you. Of the two, .270 would be the more powerful round. Both are substantial for hunting something like deer, although the .243 is probably better suited for the experienced hunter, whereas the .270 would be a little more forgiving to the novice hunter. The .270 is a necked down .30-06, and the .243 is a necked down .308.
The Mark X in 30-06, 270, 308, 300 Mag w/24" barrel will generaly fetch about $300-400 in good condition.
They can range from 100-20000 or more USD
308 Rifle can hit a target over 300 yards away. The military used them as sniper rifles and they r more accurate than a .223
The .308 has a shorter cartridge case, and a fatter bullet. The .270 is based on the 30-06 case, about a quarter inch longer than the .308 case.
Depends on your definition of better. All 3 are capable of taking any game found in North America. The 8mm Mauser carries a little more energy than the .308. The .308 may have an edge in accuracy. The .270 is basically the 30-06 necked down to .27 caliber, shoots flatter, due to higher velocity. This is one of those Ford/ Chevy/ Dodge discussions.
