We are 68 million and between hunters and sport shooters we have 5 million firearms owners for 10 million firearms. It's not on par with the US of course but I'd say firearms are pretty common (and it's not even counting illegal ones) and frankly it's not difficult nor long to acquire a good bolt action rifle and learn to shoot an apple at 200m. Long story short: I don't think lack firearms control is the issue in the US, there must be something else.
