First trip to the range. 100 yards, 15 rounds, one flyer just off the target to the right. Sights at 200. All 140gr Hornady SP, but various charge weights of 4895, around 26 grains and 1,800fps,  or so,  give or take 100 or 150fps. I still have not figured out the sights and the hold, obviously. I hope to get much better with some experience and when I find the load she likes.  Really a pleasant rifle to shoot.

Are you using loads published in a loading manual or are you freelancing?  That seems pretty slow.  (You might read the thread on the British krag incidents to see what happens when you go too low.)  Secondary detonation issues.  I have found that with my Norwegian Krag with their longer chambers and often over sized bores when compared even to the SE Mausers tend to show lower velocities per similar round than the Swedish guns.  (Comparing similar barrel lengths to keep it honest of course)  I worry that people read all the low powered load advise on the internet and then make ammo that is ridiculously low and perhaps even more dangerous than a slightly hot rounds.  Every load I have made using the Hornady book seemed to be about as low as I would want to go.  Opening loads are even on the low side I think.  Try IMR 4350 or N-160 with 139-140 gr bullets.  The Lyman manual seems to be a little better IMO for this gun.  The old speer manual seems way too low and out of line with everything else I have seen.  I read some place that they blew up a SE mauser when making it....
Have you seen the load data from Norway for safe loads for the Norwegian Krags?  They are not hot rounds but they are hotter than you might think. 
144 gr sierra MK with between 42.0 - 43.5 grns of N-160. 2449-2492 ft/sec.  Those are published loads from Norway
