Right now there is no Air Rifle, Cocking Ratio or Gas Spring for that matter.
By doing a little research, I was trying to determine which of the three color coded Gas Springs would
best serve my need as I attempt to build my own Gas Piston Air Rifle.
I have heard of and seen the mathematical calculations that would determine "Cocking Force." However;
I'm not that far along yet. Some of the other good guys on this forum were nice enough to supply a link and
some explanations of how these calculations work.
