The Fortner rifles are currently the most used biathlon rifles in Olympic competitions. The 1727 and 1827 share the same action, and the main upgrade with the 1827 model was a different stock and barrel. The straight pull mechanism uses 6 ball bearings to lock the bolt.

Smallbore biathlon rifles used today are usually chambered for the .22 LR (5.6×15 mmR) cartridge. Temperatures below 0 °C (32 °F) can have a significant effect on the reliability and accuracy of most rimfire firearms and ammunition, and some manufacturers therefore certify their production rifles by recording group sizes at for example −20 ...
These rifles are designated BI-7-4A. [23] Krico 360S straight-pull (sometimes referred to as S1 or SI) [24] was mechanically equivalent to the Anschütz 1827. The Anschütz 1727 F is a straight-pull hunting rifle chambered in .17 HMR or .17 HM2 and produced since 2013 which has taken a lot of inspiration from the 1827 F biathlon rifle. While ...
Straight-pull rifles differ from conventional bolt-action mechanisms in that the manipulation required from the user in order to chamber and extract a cartridge predominantly consists of a linear motion only, as opposed to a traditional turn-bolt action where the user has to manually rotate the bolt for chambering and primary extraction.
With short-range rifles and the lower-recoiling long-range rifles, many competitors shoot "free recoil," where the rifle is not touched at all, save for the finger on the trigger. The sandbags provide all the support. By allowing the rifle to move freely backward, the shooter hopes that the movement under recoil will be as consistent as possible.
The .22 long rifle, also known as the .22 LR or 5.7×15mmR, [4] [5] is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles , pistols , revolvers , and submachine guns .
The rifle to be designated the Model 52 was designed from the ground up as an "accuracy rifle" — the world's first production .22 to be so conceived. It was initially hoped that the Army could be persuaded to buy a bolt-action smallbore training rifle in addition to-or in place of-its existing contracts for Model 1885s.
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
