Although #5 type plastic containers are said to work best, I have read where #2 will work for PC tumbling. Wanting to be able to tumble larger batches, I got my hands on a large (1+ gallon) jug that body building bulk-up powders come in that are #2 plastic. But I just couldn't get the static cling needed even after many minutes on my drum tumbler.
For some unknown reason I had never considered using/trying one of my 8" PVC pipe drums similar to what I use for wet pin brass cleaning. When I made up my wet pin drums I made one without any vanes inside it for possible dry media tumbling. In short I had mostly never used it. Well the other day I tried it for PC tumbling and it worked WAY MORE BETTER than I ever expected. I successfully PC'd two batches of 300 each 9mm boolits. I did need to use air-soft BBs just to keep the boolits from banging into each other too much. Days later the static cling remains and is still holding powder against the inside of the PVC drum.
Just offering up another option for shake and bake PCing of larger batches.
Attached are picks of my wet pin tumbler from more than a few years ago.
