Peterson Match Casings .375 CheyTac Brass Cartridge Cases – Box Of 50

Prior to Peterson Cartridge making .375 CHEYTAC casings there was only one manufacturer making that brass available in the US. They were international. It was generally out of stock. And we are told, it wasn’t very good. In 2015 we were contacted by CheyTac® the company, and asked to develop the tool packs to make .375 and .408 casings.

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. Because not everyone knows the caliber by its metric designation our headstamp normally includes both the imperial and metric designation.

Peterson came out with the calibers in 2016. Since that time we have never been out of stock, and we run it as often as necessary so we never are out of stock. It seems this constant availability has led to a resurgence of the caliber. More and more guns are now being chambered in it.

Continuous availability of good brass could be one reason for CheyTac® growing in popularity. Another reason could be the fact that it is a fantastic Extreme Long Range (ELR) caliber. 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.
