How do you test fire a gun?

With a rifle scope. You should use a good stand to ensure that the gun is stable. Aim the barrel in the direction and focus the telescopic sight on the target. You can then start test firing. The target should be large enough and complete. Try different settings when shooting until you are satisfied with the results. Check the gun again once or a few times at a later date.
