In my old age of 34, I have recently wanted to buy a Browning BL-22. This was the first rifle I ever shot. I have great memories of shooting this rifle with my father and my older brother. My father no longer has his so I was thinking of buying one. Are these good rifles? I know nothing about them and was wondering if someone could shed some light. I've seen different "grades" of these rifles that I know nothing about. Any info would be appreciated. Thanks
