As an update, ammo is easy to find now.
My daughter bought me 5 boxes last Feb. for my birthday. Yes, she is the perfect daughter!
I nailed 4 or 5 gray squirrels the last day (Jan.31) with the WSM and a big tom feral cat. I was using 20gr fodder. The cat was about 80-100 yards distance. The 20gr pill passed clear through at an angled body shot. The cat was dead before it dropped.
Weather turned bad that day, was raining and turned to snow with the wind picking up.
We have a new Dick's store here now, just opened. They have shelves of ammo. I haven't seen any rimfire at our local Wallyworld for a long time but now they show some on their shelves. I am sure Dick's will cripple Wallyworld. No rimfire at Wallyworld for so long because it was being scarffed up in the back room up before it even hit the shelves, I suspect.
