20g minimum in Sweden and only single barrel shotguns with slug are allowed. You also need the bigame part of hunting education even then you can own the gun for smallgame hunting. Rifles are the common weapon for wildboar they are more versatile then you also hunt other biggame not allowed to shoot with slugs.Would they even be legal in some European countries?
Perhaps I am just dreaming it but I have a very vague recollection of a shotgun minimum calibre for boar in France for instance.
I have no doubt that such a gun and load would be very pleasant to shoot, but being the wuss that I am I would want something with a bit more clout for driven boar.![]()
