To test return to zero, you first establish a baseline zero by firing a group. Then, you remove and reinstall the barrel, fire another group, and compare the impact points to see how much the zero has shifted.

Does the Terminus Zeus action provide a reliable return to zero after barrel changes?

Based on a rudimentary test, the Terminus Zeus action appears to offer a very close return to zero after multiple barrel removals and re-installations, making it suitable for applications where quick caliber changes are needed.

What ammunition was used in the Terminus Zeus return to zero test?
