375 Terminator

 

You have entered the home of data for the Terminator family of cartridges. Like all loading data this is just a guideline to help you and not absolute information. This is simply what worked for us in just one or two rifles with our lot of powder, bullets primers etc. It is still your responsiblity to follow safe loading practices and make your own safety decisions.  It is not a safe loading practice to take your rifle chambered in one of these rounds even though we built it and simply start with the max load. It is still a required practice that you safely work up to a safe pressure and load. Load date can change from lot to lot with components, ambient temperature or any other number of factors. Please be safe and use this info as a guideline. Have fun and good shooting.
