Season - they breed through til september.
I'll also offer any guidance you want - I've been airgun hunting all my adult life, and now into rimfires and shotguns too.
You are welcome to join me on my permissions and I'm happy to show you the full works -marksmanship, fieldcraft, cleaning shot quarry, skinning, butchery and cookery.
It may speed up your learning curve (I had to work everything out for myself when I was younger and it took time!).
Good first post though - well done on embarking on a fabulous, productive hobby
