Regulator

[ksreta]

HI! Has anyone here ever had / tested a regulator for bigbore? I talk about Recluse, Career Ultra and other two reservoir guns(But why not others as well!). I started thingking about what kind of shot string i would get of my Career Ultra with regulator. Would it even be possible to make?

In the Netherlands we shoot Big Bore's  like the Sam Yangs and Fire's  from the Scuba with a external regulator.
This gives very good results in accuracy.  We use a hose 1 1/2 meter long.  This is only benchrest.
Dis-advantage? You shoot a hole lot more pellets and empty your scuba quiker. Also an advantage you don't fill all the time. 

Though Huub74 and Mark make internal regulators for mainly Hatsan, AA, BSA there were some rumors they have a plan for the bigbore's.

The problem is that the airtubes are much smaller then other brands mentioned,
The average pressure for a bigbore is somewhere 170 bar.
This is at the moment the top of the "normal" Huub74/Mark regulator

May be the internal regulator for the small tubes is about to be born although many others say for the use (benchrest) the few shots and multi use for other guns you better take an external regulator.

For out hunting/walking an internal regulator could have an advantage.

The problem with regulated big bores is that ideally you want about 1 cc of air "on deck" between the regulator and the valve for each FPE you want the gun to deliver.... If you don't, you have to increase the regulator setpoint to keep the AVERAGE pressure during the shot up to compensate....

What i noticed with the AA 510 .25 with an internal regulator set at 150 bar connected to a scuba that it took a "second" breathing air from the scuba.... does this means the room / chamber behind the regulator is to small?

If you mean "second" as in time, that would be normal.... regulators do not operate quickly enough to replace the air downstream during the shot.... That is why you want reasonable volume between the reg and the valve....
