Spring rate?

I know what is is but never seen it quoted on an air rifle mainspring.

To be honest it's the crux. Spring rate is the key to all this tomfoolery

The spring rate is important, Matty, but it's only part of the mix.

What's most important is the amount of energy that the spring makes available to the piston (total energy minus energy in preload), the static force (the force on the piston in the 'at rest' position), and the force on the piston at the point of release. For any given spring, all of these will vary according to the piston stroke length and preload length.

If the thread grows as I hope, Tony, there could be too much information for that. Let's see how it goes.

Anyone looking for specific information, say on Titan springs, or spring for a particular airgun, can use the 'Search this thread' option to find what they want.
