I finally got back to this one. Too bad all the pictures were gone.

I bought a second stock from Jesse at https://www.prestigiouswoodstocks.com. The wood was certainly beautiful - walnut is lightly marbled on the butt, swooping up through the wrist, then straight down the forend - as if the tree grew that way because it knew it would go on a krag someday. However, there was no tolerance under the receiver, under or around the tang, to balance the action. Out of the box, I had to make a shim of 0.100 to go under the tang. The area around the forward screw is also to low. Out of the box, I'll have to file a couple threads off my front screw as it bottoms out in the receiver. I emailed Jesse, and he was kind enough to correspond with me, and seemed interested in improving his pattern. I think he uses a CNC setup, instead of a manual duplicator like others. I did my best to level out under the receiver without messing with the area around the front screw. This was a few months ago. I got frustrated I wasn't getting a perfect fit, and wouldn't be able to no matter what. Two stocks now, same problem. Not enough material around the action to get even bedding under the tang, under receiver, and at the muzzle. So I quit and moved on to other things to let my confidence build up again.
This brings us to this long weekend. I decided I would finish it - regardless of the fit. Jesse's stock was too beautiful to give up. And his handgaurd is finished - except for rivets and bands. I accomplished the following:
1) The recoil area was a bit chewed up with tool marks, but I evened that out easy enough without setting the action back too much. The bolt recess was similar, so I chiseled it smooth.
2) I had no choice. With the front screw tight, the muzzle is off the forend by over 1/2". If I shimmed under the tang or receiver to fix it, the top of the tang would sit proud of the wood by over 1/4". And as I said, I have no wood under the receiver or tang to balance it. So, I fit the front band to the stock. I had almost 1/4" of material to remove. This allowed me to get measurements for where the lower band would sit. This has to be fit to the stock AND barrel.
3) The lower band only slid on maybe an inch from the muzzle before it stopped. The forend of this stock was not tapered to the muzzle like my original. It was spot on with no tolerance where the band sits, but fatter at the muzzle area. And, the top of the sides are not curved slightly inward like they should be. So, I spent all day Sunday re-profiling the forend to get the lower band to slide down.
4) Without removing any material from the underside where the lower band sits, or the top wall, I slid the band down to it's shoulder. Before fixing the forend, I measured and calculated that I would have 5 thous. gap above the barrel. Well, I was close. the gap was 10 thous. Easy enough. I sanded a few dozen long, even strokes across the top and all is good.
5) I next fit the butt plate. Not much to do. to get it to sit flat. It was spot on -- too perfect. There is NO room for sanding around the edges, especially around the toe.
6) I tightened the barrel on all the way (some parts of krag stock fitting are way easier with the barrel off) - double checked headspace and extractor cut. I think I mentioned before that the criterion barrel's extractor cut is slightly off. Tightened until the sights are level with the top of the receiver, the witness marks line up PERFECT, but the extractor cut is slightly off. It's not too far off, but just enough to make the extractor stick when opening the bolt. Lapping the side of the extractor claw made it work. Any worse and I would have had to take the barrel off to file the extractor groove wider.
7) Today, I made a shim to go under the tang, glued it in, chased the rear screw hole after it dried, then used chisels to hide it. I tested my wife and asked her to look it over and find where I glued in a repair piece. She couldn't find it.
8) Then, starting at the forend, I began my final sanding. Last place to sand was underside of the butt. That's when I noticed that there was no inletting for the rear swivel! Well, I traced it out and did it by hand with an exacto knife and hand chisels. First time doing anything like that from scratch! looks perfect and sharp.
9) doing the rear swivel reminded me I need to drill for the lower band retaining pin. Need to make a pin out of a nail. I have brass or steel. I think steel is correct. This will have to wait till next end, along with inletting the handguard for the sight.

I'm debating on how to finish the wood. It's so nice, I think I will do a red-oil and sand it in to close the grain. I'll try to get some progress pictures out this week.
