.375 Cheyenne Tactical – Reports From the Field

Tuesday, September 22nd, 2020

We sent .375 Chey-Tac brass to Pete Contacos and Wess Lipka for their own personal load development with great results. Wess was shooting a competitor’s brass and was able to get decent results. Hearing about our patent pending ATB® internal cartridge chamber design he wanted to see what all the talk was about. Here’s what happened:

The ATB® combustion chamber in the .375 Chey-Tac added 70 fps of velocity during the first testing. Wess is doing further load development and we will post more updates on his progress.
