Long or short refers to the length of the cartridge the action will handle. .308 (parent case of the .243) is a short action.
Short action. Based on the .308 Winchester
.243 is a short action- it is based on the .308 cartridge necked down- and .308 is a short action. 25-06 would be a long action (parent cartridge was 30-06)
Yes 3006, 270 is a long action 308, 243 is a short action.
.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.
Ruger American Rifle short action calibers (.243 Win, .308 Win, 7mm .08 Rem, 22-250)
you could put a 243 barrel on a long action, but, you'd have feeding problems with feeding
I believe it is considered a short action. Hope This Helps. Actually, The .308 is a short action cartridge, but has been sold in both long and short actions. It is a shortened version of the 30-06 case, and as such, will feed fine. A long action can feed anything based on the same parent case. The 308 is a shortened 30-06. The 270 is a necked down 06. the 243 is a necked down 308. All will feed fine. Most .308s are short action, but there are a great many that are not. For years savage never made a short action, they just chambered long action rifles in those calibers.
Short. Compare cartridge overall length to a .308 Winchester. That is a short action. Longer than that is a long action.
Long action. .308 and shorter- short action. 30-06 and longer, long action.
