The factory open sights of pre-1964 Winchester Model 94s in .30-30 came zeroed to strike within a 3 inch circle drawn tangent at 6:00 inside a 6 inch black aiming bull at 50 yards. Normal sight picture with open sights is to take a "fine" bead in which the front sight is drawn all the way into the small rear notch, then using the bead to take a 6:00 hold on the bull, using factory loads, with the sight elevator set on its lowest notch.
Each step on the open rear sight elevator increases the zero range by approximately 50 yards or meters. Raising the open rear sight into its second elevator step with the correct height of front sight height should be zeroed at 100 yards, the third notch at 150 yards, and the 4th notch 200, using a "fine" bead, drawn down completely into the small notch, and taking a 6:00 hold.
When using semi-buckhorn factory open sights for quick combat range estimation, the shoulders of an FBI silhouette or Army "E" target approximately fill the width of the small lower notch at 100 yards or meters. If you can see daylight there around the shoulders of the silhouette, the target is farther than 100 meters and to make a quick shot at a fleeting target without stopping to adjust the sights, you would then alter your sight picture so that the bead "floats" above the fine notch.
When the bead is leveled with the first shoulder inside the semi-buckhorn, above the inner notch, point of impact approximately coincides with the center of the bead at 200 yards. Proper sight picture, being altered from the base 100-yard zero, then is to hold for center of mass of the Army “E” or “F” silhouette.
At longer ranges, the hasty combat sight correction is to raise the front sight relative to the rear notch so that the bead "floats" between the top ears of the semi-buckhorn open sight. The bead then subtends the height of the silhouette and provides correct elevation to approximately 300 yards or meters.
Receiver peep sights should be adjusted to a base zero which exploits the optimum trajectory of the .30-30 cartridge. Using factory 170-grain loads with a bead front sight and ghost ring aperture the rifle should be zeroed to strike 3 to 4 inches above the front sight at 100 yards, or 10 cm high at 100 metres on a metric range. This provides a point of aim = point of impact hold, covering the target with the bead at about 170 yards, hitting 3 inches below a center-of-mass hold at 200 yards and 10-1/2” below center-of-mass, into the lower half of Army E or F silhouette targets at 250 yards.
Using correct sight picture, with a correct base zero, a game warden or state trooper qualified as Sharpshooter or better should average 80% hits or better on the Army "E" silhouette at 200 yards, 70% or better at 250 yards and 60% hits or better at 300 yards. The correctly zeroed and managed .30-30 lever action provides hit probability fully equal to the Soviet SKS and is more accurate than typical AK platforms at ranges exceeding 100 yards or meters.
