My 1898's barrel slugs out at .308 and is in relatively good shape too.  Before I got a hold of it, it spent a couple decades in my dad's gun closet and was rarely (if ever) fired.  Before that, it spent 50 years under the bed of the man who brought it home from France, so I imagine that it's not had too much use in the last 90+ years.  Anyway, I think she shoots great!

That said, this spring, I may spend a little time at a 200 yard range and do a little testing of rounds with both the 200s and 250s... and figure out how my Krag responds to both off the bench.  Once I get that sorted out, I'll create my match ammo for the years matches and I should be good to go.  It's important to remember that not all Krags "Like" the same foods... so what works in your Krag may not work so well in mine... or in others.

Still, as I said before, your work will be invaluable for all of us to follow!   :D
