Keep them in good condition ,
Here's my 2 cents .....
Everyone is collecting the 1980,s and 90's mossy oak remington shotguns like crazy , the most over looked model by far is the mossyoak sp10 with plenty of them out there going for 600$
I see where folks looking for the M.o. Slings --- people collect this stuff
the box is mossy oak -- I say it is a potential collector item , if you can find the 12 gauge versions for cheap , I would say they would be a nice accessory to go with you collection , don't pay more than 5 to 10 $ a box
But to tell you , you put that shell in a sp10 , it will kill a turkey , I'd bet the farm on it
