CheyTac M - 200 Intervention The CheyTac Intervention is an American bolt - action sniper rifle . It is capable of delivering sub - MOA accuracy at a range of up to 2 , 500 yards ( 2 , 300m ) . It is the primary piece of equipment in the CheyTac Long Range Rifle System ( LRRS ) . The Intervention was designed as a Soft Target Interdiction System for use at extreme - range . So this makes it the best sniper ever . Long Range Rifle System . Cartridge . The . 408 Chey Tac fills the gap between the . 338 Lapua and the . 50 BMG , but is said to outperform the best . 50 projectiles . Inventor Mr . Warren Jensen stated that " the . 408 Chey Tac was the first bullet / rifle system that utilizes a balanced flight projectile . To achieve balanced flight the linear drag has to be balanced with the rotational drag to keep the very fine nose ( meplat ) of the bullet pointed directly into the oncoming air . It should result in very little precession and yaw at extreme range and allows accurate flight back through the transonic region . This is hard to achieve for small arms projectiles . Mathematically you are at a great disadvantage trying to achieve balanced flight with a lead core non mono metal bullet . The rotational mass / surface area ratio is too high " . CheyTac has patented its balanced flight projectile . Sensor Package . The Kestrel 4000 sensor package measures the wind , air temperature , air pressure , relative humidity , wind chill and dew point . This information is fed directly to the tactical computer . Tactical Computer . This handheld computer is used to aid the shooter in achieving optimum results from the computer . The following variables are programmed into the computer : ° Slant angle from rifle to the target . ° Correction for air temperature . ° Correction for air pressure . ° Correction for ammunition temperature , powder burn rate , and muzzle velocity . ° Correction for rifle barrel twist rate . ° Correction for the spin of the earth ( Coriolis ) . Operator inputs the latitude on the globe and direction of fire from true north . ° The operator can input corrections based on his differences from the computer fire solution to the solution that strikes the target° The operator can also input variables to compensate for gunlock times and operator reaction times for engaging moving targets . The computer is also programmed with all current US Sniping Cartridges from 5 . 56mm to . 50 Caliber along with numerous other long range rounds . This makes it usable for sniper teams at all organizations and weapons systems . The tactical computer provides the following solutions : ° Elevation and windage settings in MOA and MIL adjustments . ° Elevation and windage settings in _ MOA clicks . ° MIL leads for use with moving targets . ° Windage solutions . The winds are input for 3 positions on the range , at the rifle , at maximum ordinate and at the target . Values are automatically input to weigh each of the three settings . ° Moving target solutions are input for speed in MPH and direction from any position on the clock . ° Danger space solutions based on the operator - input size of the critical kill zone ( 30 inches on a personnel target for example ) . The danger space dimension is a figure that tells the shooter the degree of accuracy required for the range determination . ° Maximum ordinate figures . ° Downrange velocities . This is used to determine if the target is within the supersonic range of the projectile . The computer is also programmed with all current US Sniping Cartridges from 5 . 56mm to . 50 Caliber along with numerous other long range rounds . This makes it usable for sniper teams at all organizations and weapons systems .
