Well, you’ve introduced the “odd behavior” additional factor, but 6000 rounds is not much at all and many recreational shooters will have that and more. Depending on the caliber, it may not even take up much space. See the attached link for a 5,000 round brick:

Sorry, link truncates. Do a 22lr ammo search and click on the 5000 option. It is $195 for 5,000 rounds.
