took it apart, and found the hammer spring hanged on the adjustment screw. fixed that, and made sure that the gas port lines up properly. New co2 gave me a hobby flyng at 567 fps... much better. i actually took the stock off and used the trigger group of a 2240 as well as a 1399 stock. now i have a cool little stretched "2250". is grouping very well and gets 26 shots that go from 570 down to 456 fps. then it shoots 424,333,279... so at 25 it gets changed. I guess an average of 525 fps is not bad. For anyone interested, numbers are as follows:
549,554,564,570,563,561,563,551,537,536,523,517,507,510,499,493,486,483,477,473,471,460,456. after that i got the low ones. this is at 55 degrees with an interval of 30 seconds between shots. I imagine in the summer i would get a little better numbers.
