My "Trail Gun" is a 357 mag 4" barreled S&W 686 with a shot capsules stuffed with #7 under the hammer and five 158gr SWC wheel weight slugs filling out the cylinder, all stoked with 5 grains of Titegroup. A Ruger MKII and 223 Contender are kept handy in the truck if a varmint opportunity arises and are occasionally swapped out with the Smith when on the farm.
