I use all the above, black rod down the barrel (Browning Hi-power) these are just rubberized rods. I also use S & W prop rods and clear Lucite plastic stands for both long guns and revo's.
Since I have kids, and grandkids in the house at most all times, I use the props and stands for getting photo's more than display. Firearms generally stay locked away in the safe.
I did see a antique corner curio cabinet at a store sometime back and thought if I could beef up the lock somehow this would be a gorgeous piece with 5 shelves of 2 or 3 Smiths on each shelf.
