Hey Jay, you and I are on the same trajectory, except you're one rifle ahead of me. I'm of the same mindset, that is, get a couple "kits" under my belt and then take the plunge. I've got a mentor and I think you should find one, too. That person likely has the hardware, and more importantly, the experience to get you past the scary unknowns. This forum is chock-full of knowledgeable stockers and riflesmiths, but it's no substitute for a builder who can actually get in there with you. If that opportunity comes your way, take advantage of it. Of course, Bill Raby's videos are almost like being there, too.
Hang in there, my brother. Look forward to seeing your handiwork work one day.
