RE: Leaving load in overnight??
 

I keep anold blanket in my truck and when I'm done hunting for the day
I wrap my unprimed gun up in it. Icarry it from the truck into the house
an vice versa leaving the gun in the blanket till I'm ready to use it again.
Knock on wood, I haven't had any ignition problems so far.

RE: Leaving load in overnight??
 

When it's raining out side,and I want to store the gun for hunting the next day, I use a spent primer with some card stock glued on the end to seal the chamber from moisture. I use a paper punch to cut out the disc,and glue them on the spent primer with super glue. I keep three,or four in my pocket,during damp weather. The gun will close up tight sealing the powder charge from moisture. Works great,and it's cheap! Ron
