And people look at me funny when I tell them I carry a .45 'just in case'.....

I had something similar happen a few years ago in that I had the stuff scared out of me. I had a big herd of hogs under my feeder and I picked out a smallish one and let rip with the 7Mag. She ran off a bit and died. The rest of them scattered and I picked another one off at a run from a pretty good distance. I waited a bit and got out of the blind. At the time, I carried a .38 but inexplicably, I left it in the blind and just had my 7Mag on my shoulder.

As I got up to the blind, I didn't get charged as such.....the hogs were coming back to the feeder. I guess they were hungry and the two dead ones didn't persuade them otherwise. I was in my camo gear but not exactly hiding. One big sow emerged from the brush 10 yds from me at a pretty good trot. I sighted down the barrel and missed point blank and I think that was finally enough for them. She wasn't coming at me per se, but she was going to go through me to get to that corn.
