I wanted to relate a story that happened to a partner and I in 1992 on a dog town in Wyoming. We caught a dead wind day two days after a bad storm. We both had custom 22 Mags with target chambers(slight engraving on the bullet as it is chambered). Both of these rifles shot the 40g Win HP 3/4" at 100.
We had packed the Mags along on several trips wanting to catch a day where the wind was calm and just "rimfire" the town. We had previously marked the target dials on the Leupold 6-20's out to 250 yards(hope and a prayer).
Well, on one trip, the wind was dead calm and the dogs were out in force. We shot and shot, and shot. We worked our way over to the opposite hill which the dogs were scattered from 190-260 yards. We started on the close ones and we were not missing much at all. We had this trick of shooting the one on the hole, then the next one, then the hole became plugged. Since there was about zero noise, the dogs just went back to eating and socializing.
We worked our way to the 250 yard mark, and killed every dog that was out.
The rancher had an agreement that I carry beer for him, and anytime that he wanted a beer, he could just come up to the truck and get a few. He could not believe the number of dead dogs, he went and got his neighbor and gave him a tour of the battle field. We picked up 4 more places to shoot after the neighbor saw the number of dead dogs.
I shot a lot of dogs over the years, that day was a lot of fun.
