get different sizes!!! lol
I started with some small ones and they did fine but then I increased my out put and got some tupperware type containers... big mistake cuz I didn't care to much for them.
Then I dished out for some Large bins (like the bins on the dillon 1050, but red) Anywhoo those are great for sorting and if you can get a couple and build a rack you will do great by having your brass easily visible yet sorted.
I always use 2 bins at a time. Like for trimming and swaging and so fourth. take one out of bin 1 and swage/trim and place in bin #2 and repeat lol
