I have been using Unique to fireform my 7TCU, but my supply is running low. I've loaded about a zillion 9mm from a 4lb jug of Titegroup and still have a bunch of that. Would 4-5gr of Titegroup under the Lee 130 give me enough gas to fireform the TCU? It is such a dense powder comparatively, that I would think that a bit of dacron might also be required. Or, should I just crack open the wallet and get more Unique?
