I have a tau-7, which I have been using 12g co2 caplets with. I do not have the bulk fill tank it came with, but the previous owner did include various brass adapters.

At Walmart they sell some kind of co2 tanks for paintball guns, and also some kind of adapter. No idea what will fit onto what.

Is there a way I can use these walmart paintball tanks as a source of co2 for the tau 7? I think it might prove more convenient and economical than the caplets.

While I can't help you with conversion to bulk fill, I can tell you that adapter is made to fit the large 9 and 20 oz bottles up where the 88g bottles would.
These are the 88g ones : http://www.crosman.com/airguns/accessories/co2/CAS2T which you've probably seen at W-M.
