Daystate PH6

[gingernut]

Just taken my cherished but neglected PH6 out of its corner.

Must have stood there for 9 months with the occasional polish and test fire.

Went to fill it prior to a shoot in the week.

Politely says it still has 190 , so that's ok thanks.

Modern Daystates not so much in my experience!

190bar is to high for the ph6. I was told to fill to 160-170 bar.

Odd that Daystate printed SWP 3000 psi on the side of the gun then.

Great rifles, another one I should have kept.
190 is fine, that's what all my older Huntsman were filled to.

I was going to sell this .177 model.

But then thought ,its worth more than I could get for it.
Unique

Maybe 160/170 is where the happy place starts .
In which case it would not make sense to fill much beyond.

Please correct me if I am wrong but I thought SWP was 'Safe Working Pressure' and refers to the maximum safe pressure that the cylinder is made to withstand . So it is not the actual working pressure of the gun. So 3000 is approx 214 bar. Not high by todays gun standards. But then most pcps of that era used around 140bar to very good effect. I think the Huntsman MK1 had a recommended 140 - 160 bar fill beyond which the valve could lock?

Cheers, Phil

Thanks phil. I knew i was right. Daystste said 160 was the fill pressure for my ph6

SWP is the maximum pressure to which the rifle can be filled and should not be exceeded. Direct quote from Daystate website: "Never fill the rifle with more than the safe working pressure (SWP) indicated on its breach. See the Official Handbook (www.daystate.com/handbooks) for instructions on charging with compressed air."

Test pressure will be 50% higher than this, at which point there must be no deformation of the pressure vessel, and burst pressure - a lot higher.

Sweet spot pressure - very much dependent of the particular gun, unless regulated.

The PH6 is one of my all time favourite rifles. I shot HFT in the very early days with Dave Brayford, he used a very modified one to great effect.
