Right now, yep, it's my favorite. I was at the range this evening, and did rapid fire and double taps at 50 yards. I'm just amazed at seeing the center 3" of the target almost obliterated after three magazine dumps.
However, if I want to shoot dime size groups, I have to turn to my Marlin 783. My pride and joy is my Winchester 9422M, but it is, and will remain, an open sight rifle, and my old eyes can't shoot it like I used to. So, for now, it's the 15-22!
