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.
