I tried a number of different springs in it, the stronger ones didn't make it any more powerful, the just made me scared to cock it as I thought they might be putting too much stress on the linkages. Silly really since it is quite an over-engineered rifle.

Chambers says that a HW77 spring will fit, perhaps it was that with alot of coils cut off that I put in. Just under 10 is good for a Falke, I don't think they are that efficient but from the factory I think they did about 8 or something.
