#1) Unload the 209 primer and leave the gun in your truck or garage. If you must bring it in the house, I would fire the gun. I have had condensationbuild up inside the gun from bring it into a warm environment from a very cold environment. Powder is more difficult to unload the pellets. Either keep it cool or prepare to fire!
#2) Depends on your individual State regulations. Michigan's Muzzleloading season also corresponds with the late bow hunting season. We also have a late firearm doe season on private land. I will take the bow if a buck shows up and the muzzleloader for the does. Check your reg.'s.
#3) I use the Team Realtree hangar to hold me gun / bow at the ready along with the rest of my gear (grunt tubes, rattle bag, etc...).
Good luck this season. Let us know how that load worked for you.
