My favorite calls are the Primos Hyper-lip Single, and the Primos Pack Bugle. They sound great and are easy to use. I’ve called in several hundred elk with these two calls. In fact, during one rut hunt a couple years ago, I called in exactly 25 bulls to within thirty yards over the course of three and a half days. Only four of them were smaller than 6 x 6 bulls. My hunter arrowed the 25th bull (a mid-350s class 7 x 7) at 16 yards.
