Forming 256 Win Mag from 357 Max

Do any of you guys have experience forming 256 WM brass from 357 Max? If so, can you tell me the steps you used and any other pertient info? I've read that the 357 Max brass is thicker/stronger in the web area. Have you guys found this to be true in comparison to 357 Mag brass? I would imagine that the cases need to be annealed - at what stage are you annealing them and what method are you using? I've been considering getting one of Todd Kindler's annealing tips. Anyone here have experience with it? Thanks guys for wadding through this and offering you carefully gleaned knowledge...
