The o-ring around the regulator needs a smooth surface within the reservoir to get a good seal. Any marks going lengthways across where the seal is sitting will cause a leak. Or, one of the two orings on the spacer (bus) isnt sealling. Again, make sure the sealing faces are clean and scratch free. D...

Very interesting stuff and very well explained . When you say restrictor screw do you mean on the reg it's self or on the rifle ? https://youtu.be/yhsC6yMuPB4 shows the fitting of a Huma reg to an S200. I was meaning the restrictor (venturi adjuster) on the rifle which is shown at 10:18 as this wou...

This makes a bit more sense to be honest ,but I personally would touch it as I'm really bad with things like this. If the power is still safely legal at the spike after the regulator has cut out then you could live with it. However do some testing with several heavy pellets at the spike area to com...

You guys sure know your stuff Its all Greek to me I'm with you Geo....i was reading the last few posts and something went "twang" between my ears made a mental note....... "do not try this yourself" If your familiar with finding the sweet spot for a fill, you will have seen the ...

If possible, try reducing the size of the regulators inlet port as this may bring the speeds up from 210-175 bar. When you fire a shot some air from the metered chamber exits down the barrel which leads to a pressure drop unless replaced quickly by incomming air. At present, at very high pressures a...

Maybe worth while posting up a full shot string showing FPS from 180bar fill down to 100 (or where the speed drops off a cliff) Its a bit of a pain as its typically waste of 80-120 pellets, a fill of air and probably over half an hour. However it's great for identifying problems and confirming your ...

DEET doesnt really repel ticks.
However Permethrin does a good job as ticks are repelled or killed. It can be mixed into a solution for treating clothing. Or, some dog bedding flea sprays contain Permethrin.

I think I'm happy enough with the results, so leaving it alone for a while although, I like the signature of 32:1 If it aint broke, fix it till it is 200Bar fill, still with the RWS H-Point pettets which were weighing between 14.4Gn and 14.6Gn 593 596 595 595 596 597 599 598 593 594 597 597 596 596 ...

Theres not a seal within the valve body for the valve stem... its a fairly close fit and the high pressure air is normally only felt in this area for a split second before exiting down the barrel. The high pressure (now regulated section) air is retained by the face of the valve sealing against the ...

Usual practice for an empty fill is to cock the rifle, so the hammer isnt pressing against the valve stem.

If it still leaks, remove the valve and check its clean and the face of valve and valve body are not scratched
