Leak out the back above 250fps??

Well I have an automag valve that is in great condition, I just went through and replaced all worn items. The problem is when ever I adjust the velocity above 250fps, then it starts venting out the back velocity adjustment hole. I checked the Regulator Piston and it's in good shape as is the seat and the regulator valve. The only thing I can possibly think of is that the regulator valve spring seems a little tight in the hole. I really had to yank on it to get it to come out. Could it be that it is sticking in that hole? I can't imagine what else it could be. I have fixed over 20 different leaking mags before and this is the first one to have me stumped.

Might want to try, turning the velocity down, dosent matter what the chrono says, try that.

If that dosent solve the problem, make shure your o-rings are oiled.

250fps isn't high enough. I play woods ball and I'll be at a big disadvantage if I'm shooting 250 or less and everyone else is shooting at 300. BTW, my chrono is accurate, I have chronoed many other guns on it without a problem.

If thats the case, then I suggest oiling the o-rings.
