Thanks for the replies.  To answer Ned's question first because others are probably wondering about this as well ... I did not check it for chambering when first received after the barrel installation. I had implied there were some issues in my initial post and in fact this rifle was sent back twice for issues related to the overall job but not involving the actual installation so I never did get to a point of chambering a case or dummy until this point. I also assumed that checking for function would have been part of the installation procedure and being preoccupied with the other issues I did not check it at that point...obviously now wished I had. 

The cases I have empty, dummies and loaded are Remington so are beveled per specs. Also it may not have been clear before but the bolt does close on an empty chamber, although initially I had to slightly force it and it took a few more cycles until it felt normal. Its was the bolt from the other 1898 that didn't close on this empty chamber and I didn't want to force it.

The bare bolt closes easily on a dummy round with no pressure at all felt against the case or bolt lug. I also tried the full assembled bolt on a new 30-30 case and it chambered and extracted with no issue if any meaning can be derived from that.

I guess at this point it would appear to be an extractor issue but what  puzzles me is the bolt face makes contact with the case when the bolt handle travel stops so doesn't appear there is room for anymore bolt forward movement to allow the extractor to jump the rim.

Due to events up until now I'd like to understand the problem as much as possible before sending it back so appreciate any additional insight.

As a few of us have stated, send it back on them. It needs fixed! Not up to you to diagnose specifically. It ain't working! You done paid good moolah for a job and you want to blast away with the Krag.

Good luck! I'm sure the gun smith will work with you and fix it and keep his reputation intact.

Keep us informed.

The same entity that did the rebarrel handled the blueing  but I believe they sent it out to be blued.  Also believe it was blued intact as one unit since the receiver was not supposed to be blued.

'mavt' - In one of your posts you mentioned trying a .30-30 cartridge case. Was this a typo?

In looking at your photos, I believe, I see a bit of 'edge' of the barrel's extractor notch on the right.

The tip of your extractor may snag on this, causing difficulty in pushing the bolt fully forward.

Also, that side of the notch may be angled inward at the top. This would impair the extractor claw from lifting upward as the bolt is rotated closed.

Since this is a hunting/sporter, (if I am correct about the problem), an easy fix would be to remove a slight amount of metal from the right-side of the extractor-hook.

I would not do this to a totally original Krag. But, with a shooter/hunter piece, I would do a little file/stone work.

And a couple more. I want to determine what the problem is if possible before sending it off anywhere.  Thanks for any insight.

.30-30 trial is interesting but would not have required the same range of movement of the extractor 'claw', as a .30-40 case.

Please read my last post for possible problem and solution.

I'm somewhat amazed and concerned here. You paid good money (I assume) for a very specialized job of affixing a barrel to your receiver in order to actually use it. The job should have been done without problems, checked for proper functioning and sent to you to use. You should not have to spin your wheels and get numerous opinions, albeit good advice at times, to figure out what is going on.

Another point is, if you fool with it and can't fix it properly and then send it back, you may void any warranty to have it fixed by the gun smith.

Save time, worry and trouble and send it back! It needs to be 100% before using it or you may endanger yourself and others!

I would have already had it back to the guy to be fixed by now.

Please be careful and send it back!
