HI Thanks for the responses, especially the assurance about the bolt design.  There is a lot written about the single lug design, and about the attempt to use hotter loads.  I don't intend to use anything hotter, in fact I'd like to find some "lite" loads, just to preserve the guy for the next generation who will own it when I'm gone.  I'm glad to hear there are no lists of unshootable Krags, I expect that was from the '03s problem, funny how stuff like that gets handed around.  I have taken this gun to a gunsmith to get an inspection, since I don't know the prior owner I can't be sure of anything.  I have inspected it myself and can find nothing wrong.  So, soon I'll be shooting up the new Remington loads I bought (for 2 bucks a round, GEEZ)..Thanks again everyone!
