Gratz!
It's thread like this that makes me feel how lucky I am to be in America. No license needed to buy rifles(including semi-auto). and we allow concealed carry here too.
I would start out small if money is a concern. something like a .22? Dirt cheap ammo means you can shoot all day with spare change.
my DO-it-all rifle would be the AR15. I'm not sure if you can own one over there tho..
