The Spanish M43 (1943) ,La Coruna or Eagle, is shorter than the standard action and too short for the .318 WR. Mediocre quality. Some consider them unsafe for modern .308Win loads.
Here is a warning on a forum.

So now the real problem arises. Spain surplused these rifles out, and they hit the American market. They will fit 7.62 NATO or commercial .308! What a bonanza! A cheap rifle that will chamber cheap and readily available ammo!

CAUTION!!!!
These rifles are not safe, and are not designed for, 7.62 NATO or .308 commercial loadings! If you have one and want to shoot it (I would!) you must use handloads approximating 7.62 CETME loads. A good starting point is to use load data for .300 Savage or .303 British cartridges. There is a lot of misinformation on the net regarding the safety of these rifles, but when putting your face behind that receiver, and starting your trigger squeeze, THINK ABOUT WHAT YOU ARE DOING! A large and well known distributor is floating a lab report that says they are perfectly safe, but they will not take responsibility when that bolt ends up in your eye!
