JL, let's take this project one step at a time. The collective ideas for the actual frame/action and barrel configuration appear to be solidifying rapidly. Ken, had commented after the tube supplier is determined that he will be contacting a couple of stock makers with profiling machine capability. I believe at that point, the actual manufacturing in the white costs will be determined. It's better to plan thoroughly than to jump into the project without a well thought out program/plan which will lead to a premature project failure.
