I purchased a 7615 second hand... mine does not have the black stock, it hasa laminated thumbhole stock. the gun is heavier than it looks... has a nice feel to it.
I have only shot it on my 40 yard range (getting whimpy, I shoot out a window and stay in the warm) but from what I see this rifle will shoot woodchucks out past 250 yards.
I assume there have been magazine articles on it, I pay no attention to them as magazines make money from advertisement... they will not badmouth any product it seems.
