Finally did it!!

[Terry1]

Did a full string earlier and the results are


Pre strip down

Max FPS 515 / 10.6ftlb
Average FPS 503 / 10.1ftlb

Post strip down

Max FPS 526 / 11.1ftlb
Average FPS 516 / 10.6

The sweet spot has moved too from 170 bar to 150 bar.

I would like a touch higher FPS though so may move the pot out to 58/59mm but will that make any discernible difference?

You’re right though, the consistency is much better.

Is that still using 18gr ?

Yes. Ordered the lighter ones from js Ramsbottom at the weekend. Best to wait and chrono them before doing anything?
