A word from Peterson… 

The parent case for the .375 CheyTac is the .408 CheyTac. The .375 seems to be more popular in US, and the .408 is more popular rest-of-world. The .408 was created as a military round, and many of the casings we make are sold to military units. For that reason, we adopted the metric designation. The metric equivalent for .375 is 9.5 x 77. The metric conversion for .408 is 10.36 x 77. As not everyone knows the calibre by its metric designation our headstamp normally includes both the imperial and metric designation.

This is a fantastic Extreme Long Range (ELR) calibre. Nailing targets at a mile is a “chip shot” for a CheyTac. In point of fact, Peterson Cartridge .375 CheyTac brass was used in the 2017 win of the King Of 2 Mile competition, where the winner rang targets at two miles distance.


Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.
