Daystate PH6

[Phil Russell]

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.

Fill a PH6 or a Huntsman MKI/II with 3000psi air (approx 214 bar) and I can guarantee it will not work. The Daystate information is a little misleading as it suggests that the rifle can be filled to the SWP stated but no more and still work. This is not so ... the cylinder may be safe at the SWP but that is not the 'recommended fill pressure' for the rifle to function as it should. I do not know if Daystate gave a warning in their manuals saying you should not exceed a recommended fill pressure for the rifle to function.

Cheers, Phil

I think the man to ask on this is Dave Brayford - he designed the PH6, after all......

Before we all get too excited I normally fill this gun to around 180.

On this occasion when I looked at my tank gauge it was around 190.
So I shot a magazine off.

Patrick you got found out that you were over filling your gun
So put your hands up and surrender
