With the Lyman 17A front sight, the Marbles tang sight allows just enough elevation adjustment to successfully engage my 6” steel disk at two hundred yards.
Results with this Stevens Favorite using a thin post front sight insert in its 17A and LAPUA Biathlon Xtreme ammunition were satisfying. Virtually no wind. There are 5 hits, if you count the one on the right support cable. The tang sight elevation was set at 9 turns plus 3 clicks.
The best (most expensive) European-made .22LR ammo can be expected to regularly keep 50 consecutive shots within about 4 inches at 200 yards out of the best rifles with the best scopes under the best conditions. (See

Unfortunately, as pleased as I am with this Stevens Favorite, with its light weight, skimpy stock and heavy trigger, it is most unlikely to produce such results. Sure is fun trying, though.
