I prefer the cheapo federal target load hulls with the paper base wad, they tend to hold up pretty well. I haven't had any issues with them melting, but I still only use them for one loading. I can get hundreds of them from the club I shoot at for free, and they take a roll crimp pretty well. I've used CCI 209s and 209M's, both with great results. Echoing previous responses, black is pretty easy to ignite, and as long as it works, it'll go bang.
