Bad weather so it was indoors chrony time . Been about a year since I have shot this rifle . Since I am only doing 50-100 yards at this time I have replaced the spring in this rifle to conserve air as well . Bullets were 15 bhn and the RB 8 bhn. Tethered and regulated to 2050 psi . The rifle is using way more air than it should and I got a quick reminder . The transfer port is leaking badly . Always has but I hope it will not be a always will . Never taken it apart and I do not know if there is subpose to be a o ring or not . May be some one that has taken one apart will speak up . Think I will take it apart this week end and see if I can seal it up . It is using 200 psi of air a shot . My 32 cal 909 is very close to this energy level on low power at 1600 psi and 50 psi per shot . Same barrel and bullets . Marvin

marvin the transfer port does not have a oring. I is a tight fit on the brass piece between the barrel and the valve. Mine leaked one time because I put pliers on the brass fitting, so I could get the valve out. I cleaned the teeth marks with 600 grit sandpaper. then I put 515 locktite on the brass piece and put it back together again. then I let it set over night. The 515 is flange sealant. If I take it apart again I will use a ez-out.

reading on a non sealed gun seeing as even the slightest leak kills the guns true performance in every way . I don't recall u ever stating leaky tport in your testing .
