What characterises .375 CheyTac?
.375 CT is a common abbreviation for .375 CheyTac. The cartridge belongs to the Extreme Long Range field. It is neither .408 CheyTac nor .375 SWISS P. Similar numbers or a shared part of the name do not mean that cases and chambers are identical.

Use the full designation for technical comparisons. A record report initially describes a particular combination under particular conditions. It does not establish a fixed range for every ammunition version bearing that name or a general accuracy guarantee.
The data section shows external dimensions and the associated sources. Performance figures belong to the stated version. Sporting classification also needs context: a specialised ELR match is not the same as every other precision discipline. The event announcement and range conditions determine eligibility.

What the dimensions mean
Case length measures the case without the bullet; overall length measures the complete cartridge. Bullet diameter is distinct from bore calibre. Sources may give nominal or maximum dimensions, so rounded figures can differ slightly. This overview is not a dimensioned standard drawing and does not establish interchangeability.
Understanding energy
E₀ is kinetic energy at the muzzle. It depends on bullet mass and velocity. These figures refer to selected examples from the sources, not every load of this calibre. Bullet design, barrel length and test conditions affect the result. A range of examples is neither a complete market comparison nor guaranteed minimum and maximum performance.
Understanding range
A sporting application distance describes a use case. Supersonic range is the distance over which a particular bullet remains faster than sound under specified conditions. Both differ from maximum flight distance. The cartridge name alone cannot provide a reliable range limit without load and condition details. These distances are neither hunting recommendations nor safety distances.
