Quick springer fine tunning question?

Remove from the rear as its the weight balancing pellet preference.

Thats what i was guessing as the delta was 0.8fpe then to 0.34fpe with the wieght in the piston and shootin sweeter.
How about 3 washers of the rear then another steel washer in the piston?

Try it, but unless you're considering swapping pellets every few shots I'd just go for the right shot feel with your favoured pellet. (While checking power with all of them of course)

I think Gecko is going in the right direction.Reduce spring shims.

Please let us know how you get on with it.
