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.
.22 Long Rifle Performance varies between barrel length and the type of action. For example, bolt-action rifles may perform differently from semiautomatic rifles. The .22 LR is effective to 150 yd (140 m), though practical ranges tend to be less. After 150 yd, the ballistics of the round are such that it will be difficult to compensate for the large "drop". The relatively short effective range, low report, and light recoil has made it a favorite for use as a target-practice cartridge. The accuracy of the cartridge is good, but not exceptional; various cartridges are capable of the same or better accuracy. A contributing factor in rifles is the transition of even a high-velocity cartridge projectile from supersonic to subsonic within 100 yd (91 m). As the bullet slows, the shock wave caused by supersonic travel overtakes the bullet and can disrupt its flight path, causing minor but measurable inaccuracies.
