This is all quite fascinating!  So here's an interesting thought:  Since the Long Range Match consists of two firings (first the Critchfield Match, and immediately after, the Viale Commemorative Match), what if I fire the 1903A3 in the Critchfield and the Krag in the Viale Commemorative?  I may not win... but I'll bet I'll be talked about! 

In all seriousness, shooting the Krag really sounds like an interesting proposition.  Since I have 200 of the Hornady 178 grain ELD-Match bullets, what would the chances be if I shot those out of the Krag?  What would my load, pressures and ballistics look like?  I may just do that instead.  It might actually simplify things for me.  I have 100 new Graf cases, and I'll order 100 more (if I'm going to shoot at near max pressure, I'd want new brass). 

According to the Hodgdon site, a 180 grain bullet loaded with 46.0 grains (compressed) of IMR-4350 should achieve 2,445 FPS at 38,700 CUP.  This is listed as their max load.  Loaded with 49.0 grains (compressed) of 4831 should give 2,425 FPS at 35,900 CUP (also listed as max).  Since I have 2 pounds of the H4831SC, I might like to used that powder for this.
