I got my grandpappy last year with a .410 pump. I've been after him for years and since he made his home in a rock pile that ran the length of the fence line between us and the neighbors I used a SG. I'd get 2-5 then they wise up and I'd have to wait a couple days before they'd get brave enough to stick their heads out again. And he stayed close to the neighbors house so I could only come in from the south.
My normal routine was to drive in from the south and work my way up the rock pile and shoot at targets of opportunity, when I made it to the corner I'd head back down the line about 1/4 the way and then back to the corner (largest population) then back to the truck.
But that day I stopped about 35' below grandpappy's hole, thinking if the next time I should bring my 20ga or even a 12ga. But the old boy got a case of the stupids and popped out of his hole and didn't notice me at all, so I drew a bead on him and advanced about 2 steps and let the 6 shot fly. I ran up for a closer shot but the old boy gave up the ghost, I'd ripped up his neck bad enough to do him in.
