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.
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.
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.
Long action. The .270 cartridge was based on the 30-06, a long action. .308 length is short action.
Main one is bore diameter. Another answer: 270=.277 diameter 30-06=.308 diameter
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.
In my opinion theyre fairly close to each other. Theyre both based on the 30-06 cartridge case. The 270 shoots lighter bullets at higher velocities but the 308 can shoot heavier bullets. I would base a choice depending on the application.
None of the above. The best, IMO, to start with is the 22lr.
The long action simply has a longer receiver, to accommodate longer cartridges such as the .270 or .30-06. The .308 should be a short action. I have seen long action .308 rifles before, but these were typically .30-06 rifles rebarreled for the shorter .308 cartridge.
The Mark X in 30-06, 270, 308, 300 Mag w/24" barrel will generaly fetch about $300-400 in good condition.
