First, you should still get better ranges than that with the stock spring. How's the plunger seal?
Secondly, using streamline's is only going to add to your problems. Going to be fairly difficult to gauge range with the dart's fish-tailing all over the place.

I believe the seal is good. If i block the barrel and release the gun it very slowly lets the plunger down. i tried with a stefan i made from an old streamline, made it worse.. heh.. I will have to try buy some darts next Sunday at the war, and hope it works.
Biggest issue i can think of is that the dart is not sealing in the barrel well enough and a majority of the air is escaping down the sides of the dart.
