Marlin makes a .308
If its a .308 its a short action.
The 30-30 is a rimmed cartridge, versus the .308, which has a rimless cartridge. The 30-30 has much lower energy than the .308, and is typically loaded with a flat tipped bullet, due to the number of lever action 30-30s that had a tubular magazine. The .308 typically has a spitzer (pointed) bullet.
Lsa -55 is a short action rifle made by tikka in finland for ithaca. It was made in .222 rem, 22-250, 243, 6mm and 308. It came in a standard and deluxe versions. The lsa-65 was the long action model and came in 25-06, 270 and 30-06. Made from 1969 thru 1977?
There is no long action 308, it's a 30-06.
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.
