Four or five, with more back at camp. Once, I was hunting in VA with an open-sighted Hawken loaded with PRBs and a turkey flew up in a tree, right at the edge of my range. I was standing behind a big pine, took a rest on the side of the tree and cut loose, clean miss.
The turkey just stuck his head up and looked around but didn't see me. So I re-loaded and shot again, same result. IIRC, I was reloading for a third shot when one of the guys down at the cabin came up to see what was going on and spooked the bird. If he hadn't done that I'd probably still be shooting....
