I try to call bear evry year here. I have had good luck, having called in quite a few, as we have a high population here. I also use 002 reed. Lots of JC reeds can be tuned pretty good to call bear though.
It is both scary and a rush to see a bear crashing in into your stand, even if you see em coming from a long ways off!
I usually only call during bowhunting season though. To many hunters around during rifle here.
