Hi guys, going out for first muzzleloader hunt for whitetails this weekend in Illinois. Pretty excited as first season shotgun was good to me (140" green score gross 10pt.). As am new to muzzleloading, everyone suggested that when i am done hunting at the end of the day, and have not discharged gun, just to remove primer in accordance with local laws, and this constitutes an unloaded weapon. My next question is this, how long can powder pellets be left in barrel without encountering firing problems (from moisture, etc)? What i am getting at is will i need to remove powder and bullet everynight upon returning from the woods, or can i leave powder charge & bullet in barrel for the 4 day season without encountering firing problems due to moisture etc?? Also, any particular kind of soap need to be used for cleaning? thanks alot guys. miles
