Personally, I don't blame you for shooting the rifle off at the end of the day. I have done the storage thing and been very disappointed. And I have tried to store the rifle in the garge, the wood shed, even the truck, but I must live in a humid part of the world because I had more misfired or hangfires the next day then I care to count. So I shoot mine off.

Since you're shooting triple seven, shoot it off and at least use some water and swab the bore. Windex would work just fine. Then some dry patches until the bore is dry. Then a lightly gun oil patch, swab the bore. Every four days or so, break the gun down and give it a total cleaning. Before you shoot the next day, swab the bore with windex or alcohol patches, then dry patches, then if you can, pop a primer through the breech plug.

Something I have been experimenting with because of all the people saying they can not shoot off a primer or cap before they go hunting. So far no misfires.I have used compressed airafter swabbing the oil out, blown through the breech plug to clean it and open it. If your shooting a #11 nipple, go to a pet store and get a length of fish tube for their tanks. It will slide right over that #11 nipple (take a #11 with you for the right fit). Then blow like the devil through there and listen. Hear the air. If it is a 209 primer, you can do the same thing, but put the tube right into the 209 hole and blow hard. That will help open that breech plug before you load it.

Now load it as normal. Like I said, if you've shot that off for say four or five days in a row, then break the rifle down and clean it. Or if you get lucky and get to shoot a couple rounds.. clean it. The concern is the breech plug. At least give that breech plug a twist to make sure it is not seizing up. Triple Seven will rust your barrel, but it takes a few days. So if you're swabbing out the fowling and a light oil between full blown cleanings. it MIGHT keep you safe. If you have any doubts, clean it.
