Congratulations! You have what sounds like a fine Krag that will serve well in the woods/fields for hunting and as well give pleasure when used at the range. Given that the bore is a bit rough, consider using loading and using 180 gr. flat based bullets round nosed bullets beginning at starting load levels and increasing the powder charge as determined by pressure signs and accuracy on target dictate. If the muzzle crown is a bit less than perfect due to wear, etc., a few minutes of polishing with a brass screw and valve lapping compound will be useful as it will very likely improve on target results.
