If I remember correctly there was a write up on a rifle build on Frank DeHass's design in The Home Shop Machinist. Not sure if it was Frank or somebody else did a build. It would likely take me a year of digging through my stuff to find it though. I used to get the magazine as well as some others, you could go to THMS web site and maybe find some info, not sure if you can look at past issues. I'm intrigued but I have way to many projects to get done before the end comes.
