Here is a chart showing the main game usually hunted in Spain. As you can see, practically all of the animals are CXP2 class and normally hunted by stalking.

The main exception is the practice of the "monteria". This particular practice is very common in the Mediterranean Forest, and involves a battue with dogs entering in a area circled by the hunters placed previously in strategic points. Normally you must shoot at running game (mainly deer and wild boar) with plenty of adrenaline in their system, and trying to avoid the open spaces. For this form of hunting it is very common to use calibers such us the 30.06, .308 or even more powerful cartridges at short distances like the .35 Whelen, the .338 Win. Mag. or the European 9.3x62 or 9.3x74 R.
