I am a bit surprised that people are recommending you leave the rifle loaded.
Good response to your question and hopefully, you will fill your tag and then have a reason clean your rifle. ....Pull the cap or dump the pan and leave it until next time.
I do understand what folks mean by "Loaded". Perhaps charged might be a better word. I Iowa, as long as you do not have the rifle primed or capped,, it's "legally" unloaded and can be transported ands stored. ......I am a bit surprised that people are recommending you leave the rifle loaded.
Ned Roberts in The Muzzle Loading Cap Lock Rifle has some things to say about it.
