have a beautiful early FWB 124 thats shooting H&N FT specials (8.6 grs) at an anemic 600 fps. I recently put in a new full-power spring and hand fit a new piston cup, also did a very light black tar lube....but after a tin of pellets, it never "broke in" and got better. Heard these things will go into the 800 fps range when properly tuned. Seemed to be an easy disassembly, after I built a spring compressor...but maybe I missed something? Breech seal is perfect. Id like to get her into the 800 fps range. Any help here would be appreciated.
