Biathlon Rifles Biathlon rifles, when compared to target shooting, are very, very similar. Generally the barrel of a biathlon rifle is shorter than one for target shooting. A magazine fed biathlon rifle is a significant advantage since, unlike most target shooting, you are competing against the clock when you shoot. This minimizes body movement of the biathlete as he loads the next cartridge and is slightly faster than the bolt action. In target shooting this isn't as big a worry.
