I have three serious hunting rifles, all Model 70 Winchesters. The .257 Roberts Featherweight mounts a long discontinued 4 power Leupold compact with a plex reticle. The .30-06 has Herters 3x9 with a Shepherd reticle. The Model 70 in .375 H&H wears an old steel tube 2.5x Weaver with a plex reticle. There is an M-4gery that sports an M68 red dot. A vintage AN/PVS-2 is sometimes mounted on an M1A with mixed results. While I can no longer hear the characteristic high pitched whine of the power supply, I believe that the coyotes can, even at a couple hundred meters.
