I didn't real all 7 pages of this thread - but the .30-30 is on the same power level as 7.62x39 (AK47 round). Works very well on hogs. We use 'em in 200 yard silhouette matches. Lever guns are less accurate than breach loaders that have a solid lock up (bolt actions, rolling blocks, falling blocks, etc.).
A good lever gun should group about 2" at 200 yards. Average lever guns will group around 6" at 200 yards - varies with the load, the sight, the shooter and all the other variables.
Buckhorn sight - good luck hitting the general area twice at 200 yards
Tang and Receiver sights - should give you a nice tight group at 200 yards
9 power scope with fine crosshairs - 2" groups at 200 yards
Red dot sight - good for that charging hog at 20 yards
