I shot the Krag this morning and the best I could do with my lousy eyesight was about 4.25 inches for three shots at 100 yards with Remington 180 grain factory fodder.
I am going to scope it.
I love the rifle
What scope mount are you going to use?
I ordered one of the S&K no drill mounts.
Better get a comb riser too, IIRC, S&K mounts are really high.
