if you got your S. G .C you are half way their . first thing to do is try and go out with same one and watch whats what ( MAY BE SAME ONE ON THIS SITE NEAR BY CAN HELP YOU ). safty is top of your list .then you need same were to shoot , and what for ,rabbit ,fox etc then what calibre , its a different ball game to shotgun,as for what rifle to have is mind blowing same people say this and others say that.
i (PERSONLY USE A 20CAL (204) ) ,FOR FOX, BUT U CAN HAVE 222, 223, 22,50 and so.
availability on ammo, is another thing . im sure their be more suggestions on their way later .
