Advantages and Disadvantages

While lever-action rifles were (and are) popular with hunters and sporting shooters, they were not widely accepted by the military. One significant reason for this was that it is harder to fire a lever-action from the prone position (compared to a straight-pull or bolt-action rifle), and while nominally possessing a greater rate of fire (contemporary Winchester advertisements claimed their rifles could fire 2 shots a second) than bolt-action rifles, lever-action firearms are also generally fed from a tubular magazine, which limits the ammunition that can be used in them. Pointed center fire Spitzer bullets, for example, can cause explosions in a tubular magazine, as the point of each cartridge's projectile rests on the primer of the next cartridge in the magazine (soft-tipped Hornady ammunition made for tube-fed rifles avoids this problem). The tubular magazine may also have a negative impact on the harmonics of the barrel, which limits the theoretical accuracy of the rifle. A tubular magazine under the barrel also pushes the center of gravity forward, which alters the balance of the rifle in ways that is undesirable to some shooters. However there are lever rifles, such as the Winchester model 88, that have a box magazine instead of a tubed one that negates this problem. Furthermore, many of the newer lever action rifles are capable of shooting groups smaller than 1 minute of angle, comparable to most modern bolt-action rifles.

Due to the higher rate of fire and shorter overall length than most bolt-action rifles, lever actions have remained popular to this day for sporting use, especially short- and medium-range hunting in forests, scrub, or bushland. Lever-action firearms are also used in some quantity by prison guards in the United States, as well as by wildlife authorities/game wardens in many parts of the world.

An additional advantage over typical bolt-action rifles is the lack of handedness. A lever-action rifle can be used equally well by a left-handed shooter.

[edit] Calibers
Most lever-action designs are not as strong as bolt-action or semi-automatic designs, and as a result lever-action rifles tend to be generally found in low- and medium-pressure cartridges such as .30-30 Winchester or .44 Magnum, although the Marlin Model 1894 is available in three high-pressure magnum calibers; and the Winchester Model 1895, which used a box magazine, was chambered for .30-06 and other powerful military cartridges. The most common caliber is by far the .30-30, which was introduced by Winchester with the Model 1894. Other common calibers for Lever-action firearms include: .38 Special/.357 Magnum, .44 Special/.44 Magnum, .41 Magnum, .444 Marlin, .45-70, .45 Colt, .32-20 Winchester, .35 Remington, and .22 caliber rimfire. Lever-action designs using stronger, rotary locking bolts (such as the Browning BLR) are usually fed from box magazines and are not limited to round nose bullet designs, as well as being able to handle a greater range of calibers than a traditional lever-action design. Lever-action shotguns such as the Winchester Model 1887 were chambered in 10 or 12-gauge black powder shotgun shells, whereas the Model 1901 was chambered for 10 gauge smokeless shotshells. Modern reproductions are chambered for 12 gauge smokeless shells, while the Winchester Model 9410 shotgun is available in .410 bore.
