Thanks for all the information!  I took it out and shot it this weekend with Remington Core-Lokt.  It grouped pretty nicely from 100.  I am very glad I picked up the Krag. 

Regarding the cracked lugs...what fps will 40 grains of powder and a 220 grain bullet do?  I am assuming that load is different than the load the Army used for the short period where they had the problems.  I am going to look into the two bullets (Hornady and Sierra) and buy some dies.  That rifle was a lot of fun to shoot, but until I start reloading it will be expensive...
