Response to HW100 .22 FAC shot string is a bit problem. Please help
If so, increase it in a couple of increments (roughly 1mm at a time is good) and take a few shots over the chronograph and report back.
To explain what I'm thinking, almost 2000psi should produce far more than 32fpe with the JSB heavies unless the porting is fairly anemic. I'm not familiar with the stock porting, nor do I know if you've modified it, but if I'm on the right track, you're operating too far down the slope to provide the best consistency.
