Response to Still more to be had

Hi Tony,
I'm also trying to set up my 1740 HiPac.
My last visit to the clubs chrono produced similar results.
I'll post my string when I get home but it did have a spread of around 100fps returning up to 30 shots with a fill of 120bar.
I need to do a test like Roberts great post on how fps spread effects accuracy.
I'd like to know how to flatten the curve and open to suggestions. I could try fill pressures and have a spare hammer/striker that I can get reduced.

I live in the UK with a 6fpe max gun law. I'm looking for a maximum number of consistent 5fpe shots.
Cheers
Ian
