Among the items for ranchers at the Cammack Ranch Supply in Union Center, S.D., is the “Dakota Dart” rifle that can deliver low-dose prescription drugs to cattle without having to round them up. The gun is very accurate at 40 to 60 feet, store owner Gary Cammack says. The technology has been around about five years but has become more popular in the past two years because it saves time and stress. (Mikkel Pates / Agweek)
