According to this http://www.cip-bobp.org/homologation...rma-mag-en.pdf the neck-shoulder diameter is 8.71mm and the shoulder-body is 14.29-.2mm, that comes out to .343" and .563-.008"

You could use either the D.4 or E.42 and be pretty close to the middle of the shoulders from what I can figure but I would go E .42 myself
