I have expanded 35 Whelen without annealing with my full-length sizer did, loaded 63gr of H4895 behind a 300gr Hornady .411 diameter bullet. The cases fireformed for the 400 Whelen perfectly. They also chonographed at 2460 fps. Counting rifle, gunsmithing costs, brass, bullets,and dies I'm into my 400 Whelen $1500.
