Grainger / Fastenal and these generic machine shop suppliers are a joke with so bad and outdated online ordering interface (at least here in Canada),

McMaster I like way better but doesn't have a large enough selection that can feed in my interest:

Compression Spring; Min ID = 5.0 mm (.197); Max OD = 7.1 mm (.279); Wire Dia = 1.0 mm (.040)

{btw this is the original FX Impact MK2 Valve Spring, free length 45 mm}

I am looking for a wider adjustability with - 30%/+0% deviation, wire Dia 0.7-0.9 mm shall do, different material specs = a bonus
 
Thanks, I am trying to micro tune the dwell time. Finding the original spring is just way too stiff/rough. In a past month I was using one WDia 0.5mm but that is too soft and assume the hammer is bauncing...

Jumped from 130 to 140 on the Reg very last day at the range, preparing for shooting slugs next, a very last five tins of JSB MK2s wont last long but with these I want to finish the Valve tune. But this FX radar is worrying me lately, missing shots and erratic numbers screwing up the SD/ES.
