Johnny,...I do the same thing...I do store my Knight in a hard case, I also keep everything in there I need to hunt with it...6 preloaded measures, a powder flask, extra bullets, discs already primed, cleaning patches, alcohol, oil, everything I would need to service and clean the gun...I put my breech plug in a ziplock bag...

This post reminded me of a problem I ran into about 25 years ago with a John Deere 850 tractor...I was a service rep in VA and those tractors were made for us by Yanmar in Japan, they came to the dealer in a wooden case after being shipped....A dealer had called, the tractor was blowing oil out of the exhaust...He was ready to pull down the engine...I went to check it out and removed the dipstick while the engine was running, I noticed he had air blowing out of the dipstick hole, the crankcase had pressure in it, which is not normal....There was a breather hose that I removed, couldn't blow through....It had a dirt dobbler's nest built in it....I took a clothes hanger and cleaned, fixed the problem....Later that day another service rep on another territory called and had the same problem, he couldn't figure what was happening and that dealer had started to dissassemble the engine....
I told him what I found and his tractor had the same problem....

Deere sent out a service bulletin on this, several in that same shipment were found to have the same problem...They started plugging the pvc hose with a red cap for shipment to eliminate further problems...
