Since I am the first to see this I'll throw in my .02 worth. I am just about sure you can use your muzzleloader for the shotgun season unless they just changed the rules, I am not a muzzleloader guy so its never applied to me. With your credit card, they process it right way (At least for me they did) even before you get your permits. They want your cash ASAP, that's how these crooks work. If you are unsussessful then they will mail you a check from the IDNR at some point. Hope this helps somewhat. Good luck!
