I have a thought........
If the object is to lighten the bolt but maintain a good wear factor....why not just flute the existing stainless bolt? Like they do to rifle barrels in order to lighten them up while maintaining the general barrel characteristics. I realize we are talking about the Bolt of the Mag....but the concept is the same. It would lighten the bolt somewhat but since its stainless it would maintain a good wear factor.
