If you want a light plinker for your Krag I've had really good luck with the 311466 Loverin boolit using IMR4227 powder. I'm at work at the moment but can give you my data later if you want it.
I have the NOE 311284 but have not had a chance to work up loads for it yet in the Krag. I am thinking of using IMR3031 with it as that powder works well for me with 180gr J-words.
