what caliber of rifle did the rifleman use
The Rifleman The rifle used on the set of The Rifleman, an 1892 Winchester caliber .44-40 carbine with a standard 20-inch barrel, appeared with two different types of lever. The backwards, round-D-style loop was used in the early episodes. Sometimes the rifle McCain uses has a saddle ring (the purpose of this ring is to allow the rider to tie the gun with a lanyard, to secure it in the scabbard). The lever style later changed to a flatter lever (instead of the large loop) with no saddle ring.
.338 Lapua Magnum For a typical .338 Lapua Magnum high end factory military sniper rifle like the Sako TRG-42 with a 690 mm (27.2 in) long 305 mm (1 in 12 inch) rifling twist rate barrel at sea level, 1,500 m (1,640 yd) is considered to be the maximum shooting distance for man sized targets. When using standard Lapua military 16.2 g (250 gr) loads it has a supersonic range of 1,500 m (1,640 yd) under warm summer conditions at a muzzle velocity of 915 m/s (3,000 ft/s). However, to be able to maintain 80 to 90% hit probability on non-moving 45 cm × 90 cm (17.7 in × 35.4 in) reactive army targets, this maximum shooting distance has to be reduced to 1,300 metres (1,422 yd) at freezing point conditions or 1,100 m (1,203 yd) in Arctic winter conditions, when the muzzle velocity may drop to 880 m/s (2,887 ft/s)—i.e. only during optimal warm summer conditions the 1,500 m (1,640 yd) maximum shooting distance is realistically achievable.[68][69]
