I've had a couple of Krags - one was an original sporterized model, that was in the family for many years. I took a doe with it, then eventually gave it to my eldest uncle, who had killed his first deer with it. He then gave it to one of his grandsons. He is an avid shooter, so I am sure it's in a good home. With one of the aftermarket peep sights for it, I managed 3 in 1½" at 100 yards, using 180gr Nosler Ballistic Tips.
I also had a Ruger #1 - one of the special editions Cabelas sold, with high polish blue and jaw-dropping circassian wood. Took an 8 point buck with it. Eventually, it went to a new home, and I made a tidy profit on it. The wood would not have been out of place on a Purdey, or any London Best Grade gun.
The Krag is an interesting and well made action; you dare not hot-rod it, but that's hardly necessary to harvest NA game.
