If you have the budget, I would look for a used Wildcat, [a gen 1 to save money]. That's a hunter's gun. For portability, cocking lever handle position and overall weight it cant be beat.
As a budget saver, the Urban and Buccaneer are good options but the magazines are expensive. If you want to carry 5 mags around, it'll cost you as much as the rifle. Of the two I'd go with the buccaneer with a threaded muzzle break instead of the bonded "pickle". They are easy to regulate also, can upgrade the trigger for cheap if you are savy with mechanics
If you are look for pure function, Hatsan's are hard hitting, a little heavy, but can be found for pretty cheap. Mags are cheap as well.
