Welcome. I am in Hobart. You may want to check out Michigan city rifle club in the spring. They shoot Rimfire Challenge all year round, but in the winter they are inside. They move outside in April.
You are not that far from Bend of the River, in MI. They stated shooting Steel Challenge last year and will start in April this year. There is also North Porter County Conservation Club (NPCCC) near Chesterton. They put on lots of different matches. They do an outlaw steel match and I see they added a sanctioned Steel Challenge for this year.
There is New Buffalo Rod & Gun Club in MI, too. They don't have a lot of pistol matches, but shoot a lot of trap. They have a nice mover target, but do not do Action Pistol any more. They do use it in November for their Running Deer matches. Also, Warsaw has a nice club with quite a few matches when the weather breaks. Below are some web sites so you check them out.
