Shot up some alternate formula Tannerite in those tiny plastic targets last weekend. Liked it a lot, especially using a 22 instead of higher velocity rounds. Can I get the same formula in bulk and load my own tagets? Plactic salsa containers, film cans, etc. The Tannerite website was nebulous and I didn't see what I was looking for there. Hope I can find the 22 sensitive powders in bulk soimewhere near Portland. Any leads? Thanks.
