The .375 Cheyenne Tactical, or .375 CheyTac for short, is a sporting rifle cartridge.

History[]

Introduced in 2009, the .375 CheyTac originally started out as a wildcat based on the .408 CheyTac. It became officially certified by the C.I.P. in 2017 under the 375 Chey Tac designation.[1] At some point in October 2020, CIP removed both the 375 and 408 CT drawings from their website. This follows unsupported claims of weapon system malfunction. Peterson, as the claimed world’s-largest supplier of brass for these chamberings, was blindsided by the CIP drawing removals and has, in response, produced and posted Peterson (effective) re-draws of the official, previously-CIP-posted drawings.

Design Details[]

This cartridge is essentially the .408 Chey Tac necked down to use a smaller .375 caliber bullet. Built on the same premise as its parent, which is of a very high speed lightweight projectile to reduce recoil, ideal for long-distance precision shooting.[2]

According to Cheyenne Tactical, the .375 Chey Tac has a slightly higher ballistic coefficient than the .408 Chey Tac.[3] Even though it was developed as a civil cartridge, Australian sniper teams were said to have used the .375 CheyTac to engage targets in excess of 3,000 yards (2,743.2 meters).[4]
