So I'm new to hunting And have been reading a lot of threads squirrel hunting. I just have a few questions that Hopefully someone can answer.
1) I own a 12 gauge is that overkill? Should I purchase a 22?
2) What is the best kind of optics for a 22 specifically for squirrel hunting?
3) Is cammo necessary for midseason Illinois squirrel hunting?
4) Are calls necessary, do they help? For $12 at bass pro I'm willing to try.... What about cutter calls?

Just want to say thank you to whoever can help me greatly appreciate the help
