I am looking to do a little predator clean up around my hunting grounds. There are a few limitations though. I can only use a shotgun. I am using my Mossberg 835 and #4 buckshot. bI currently have a Primos Tightwad choke on it for turkey season. I also have a nice Patternmaster Extended choke tube. I haven't been able to pattern them yet. I was just wanting to heard what some of you guys are using to thin the coyote and bobcat population. What ranges and patterns are you getting. Let's them.
