The .270 Winchester is a long action cartridge. It is a .30-06 Springfield necked down to hold a .277 caliber bullet.
Yes 3006, 270 is a long action 308, 243 is a short action.
No. The 270 is based on the 30/06.
.308, and its derivative cartridges (like .243 and 7mm-08) and generally short actions. 30-06 at its derivatives (like 270, 25-06) are long actions.
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.
Any short action will fit.
