a few weeks ago I went out to one of the duck farms to do some rat hunting. It was very cold and I have a favorite spot that I can park my truck, shut the lights and shoot out of the window. I had brought my friend along as well. He is a non hunter but comes out with me once in a while when he has nothing to do.
Well, every now and then I turn on the spot light and take a rat before they rop into their rat holes. I was shooting the Sumatra and I was shooting really well that night and my buddy was confirming my hits. However, I couldn't see the dead rats. Often, they will have enough strength to make it to a hole but the shots I was taking where head and chest with a Kodiak going 900fps. In other words these shots were rat anchors.
Finally, after whacking four rats and not seeing them laying there I decided to venture out along the barn to see what was going on. The four rats I had taken all had come up out of the same hole so I only had to walk to one spot and move some feeder boards to see under them. Understand that tehse rats are huge from eating duck feed and the are gross because essentially they live by tunneling under a foot of duck poop and straw. "Yeck" Rats sceeve me anyway but these are extra sceevey.
Of course as I walked out in the dark my buddy did his best impression of rat noises and would report on the one that was headd for my pants leg. It was a good laugh. I removed the feeder boards and finally understood what was going on. Essentially. each rat had poked his head up, gotten shot than fell dead into the wide opening of the hole. I later found a stick and moved the bodies and you guessed it, all four were piled in the hole., In the pic below you can see two tangled up at the top of the entrance.
So, after the first rat was killed , each of the subsequent rats had pushed up through their dead buddies to get killed themselves. "Yuck, yuck and yuck"
