I love #1s.
I have owned 3 but now I have only one. I had two 270s and one 243. I now have a 9.3X74R. I wish I had kept one of the 270 now, but I was dumb enough to let someone buy it from me.

The 243 I gave to a girlfriend years ago. I hope she took good care of it and made a lot of meat with it, but I don't really know.

It would be hard for me to name one rifle as "my favorite for hunting" but if I could name 3, my #1 is always going to be in that group.
