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.





375 Terminator


Load data will be up as soon as we make some tweeks to the brass. Bertram Brass has been working with us on this and we appericiate all their efforts.  Since the 375 Terminator has no parent case the best description of the 375 Terminator is as follows:


Case body similar to a 375 CheTac, but .500" longer.

Rebated rim to Super Magnum / Lapua (.585" head)

Neck is longer than the 375 CheyTac

Capacity is in the 185 gr H2O range

Appears to want to push the Cutting Edge 400 gr. Lazer bullet at 3050-3150 fps out of a 34" barrel

We have already "proofed" this round in our Terminator action at 170,000 psi without any metal failure.


When we have the all squared away and tested I will make a full release of our biggest Terminator.
