Cutting coils off an air rifle mainspring.

This is my successful attempt at cutting down an air rifle mainspring. Following the instructions of Davy T of the Vermin Hunters in is vid on their channel. The spring was a Titan XS No.7 spring, I cut 5 coils off so it would fit in my ASI Gamo Cadet. Having put it all back together I reckon it could do with another 2 or 3 coils coming off. I'll do that soon using this same technique. Cheers Jim
