Anyone have any feedback on these kits for a Model 70? How easy is it to screw up?

I’ve known Charlie Robertson for many years, and have used his Pro-bed 2000 almost exclusively for about as long. His kits are very complete and instructional videos are great. I personally don’t pillar-bed flat bottom actions but his kit is great.
