I am about to go predator hunting for the first time this weekend and plan on using my remington 870 (20 gauge) and my Marlin 336 for longer shots. I have tru glo sights and a primos jellyhead extra full choke on my shotty so I hope these help. I also got a H.S. Johnny Stewart coyote hooker call. I plan on getting a cottontail in distress call and mouse squeaker to actually grab their attention though. Good luck!
