I use those buckets with gamma lids to store base malt.
BUT! you should have waited another six months, just for giggles. Bumping a 9.5 year old thread is a solid necro-post, but you didn't make the decade club.
Yep, I've got a bunch of the white Lowe's with the Gamma lids. Pretty sweet combo for storing salt, birdfood, brewing malts, etc. Though, if you buy base malt by the 55# bag and you want a larger container with the same gamma lid, get this: stackable too, in case you want one for pilsner and one for pale malt.
