You don't want to put anything else into the bag. They have something built in, in fact you don't want any excessive oil or lube on the firearm. Thats why I put some lube in the barrel with the cache, but not in the bag. The loaded mags were in a separate bag.
I think they recommend NOT putting ammo in the same bag.
They have long gun bags as well. I had a 10/22 in one all last winter that I opened this spring, it did well also.
I got some of these last winter, I thing from Sports Academy.
I wanted to test them before I depended on them. I think they work very well.
They are spec'ed after what the military now uses at their armories. Probably once they started having trouble with that real fine dust in the Middle East.
Don't know what is built into the bag, nothing I can see or smell.
The first ones I bought required me to stretch the bag when opened and not to open the bag until I was ready to use it. Also not to reuse the bag once it had been used.
But the newer ones don't have that requirement.
I had some rice just loose in the bottom of the barrel, but nothing in those bags.
I had some other mylar and plastic bags in the same barrel.
I had used rice in sealed tubes/cans/buckets/barrels with good luck before, but one I opened this spring that I had a leather holster in, everything else was OK, but the holster had grown mildew. The handgun in the holster was fine but not the leather. The insides of the holster had been oiled.
So I have some leather goods buried the same way now but now but I rubbed some of them good with neatsfoot oil
en.wikipedia.org/wiki/Neatsfoot_oil and some in saddle soap.
The holster was "spit shined" with black polish on the parts that show but was just raw leather on the back.
I should have known better, I don't put my boots into storage with raw leather untreated, but I had never had a problem before.
Redneckokie might have some "tricks" to use to store leather goods.
I went to nylon holsters for storage after that.
