Currently my inventory of rifles and shotguns are standing up (barrel up) in my home office. We are getting ready to move and I am looking to buy some soft side gun cases for some of them. I' m not sure where I will store them when we move.

1) Is it OK to keep them in a gun case standing up in a closet?
2) Would you recommend getting one of those Silicone treated " Sack-ups" to go in the case as well?

Any other thoughts?

Thanks
