It is a fun cartridge. One MOA is no problem. I found the throat on mine is quite long, and 150 NBT were the lightest bullet that would allow the bullet close to the rifling, and still have a little purchase in the case neck.
It has since lost the overly-large scope. On the semi-minus side, I gave my original Krag to an uncle, so none of the Ruger loads would find their way into an old rifle.
I may just put a peep sight on it, and use it on hogs & deer.
