I have the need to put some long guns in long term storage due to the high price of ammo, I do not reload. I was looking at using Zcorr FSP bags. They cost  $13.00 for each bag. What would be to proper way to prepare these long guns for extended storage? They will all be cleaned prior to storage. I will keep them in a unheated summer home in northern Wisconsin where it gets 35 below zero in the winter. I assume that the scopes have to come off the scoped rifles. One of the rifles is an M1 Garrand with a walnut stock, the rest of the stocks are synthetic. What products should i use, and should i grease the inside of the barrels?

I have to say, that I don't know what I'm doing wrong, but the search function is useless to me. I rarely get any results, even when I know the subject has been discussed within the past day or two. I find it very frustrating, especially after getting no results and then starting a thread, only to be told to do a search.
