Yes I do still have it. I signed up for the world's shoot and have been trying to shoot as much as possible with it. I am no where even going to compete with those guys but I plan on using this. There really doesn't seem to be a lot of information on the internet about these

Looks good!

The "compression ratio" issue is not a problem - you won't be overloading the second stage, as these pumps basically balance the load through reed type valves. Compression load is basically split between the two cylinders dynamically as pressure increases - these are not fixed closed cylinders like in a car engine - the pressure "leaks out" into the next stage when the pressure rises above what the valve has holding it closed. So you are actually reducing the relative compression load on the cylinder by feeding under pressure.

Think of it this way - when boosting from 1 bar to 300 bar, that is a 300 times increase in pressure in two steps. The square root of 300 is bit over 17, so at 300 bar both cylinders are basically compressing at that level. By feeding it 6 psi, you are feeding it about 40% more air, so it is starting at 1.4 bar. We have to "normalize" that starting pressure out in a two stage system, so booting that 1.4 to 300 bar would be a 214 times increase in pressure (300/1.4). So now the square root is under 15, so less actual compression takes place (40% less, although the pressure is the same at the output.)

This is a good thing, but I would not go overboard on it - I would not go over 2 bar absolute, or about 15 psi gauge, on the input side just out of caution. That said, you could test the stress on the compressor itself indirectly by measuring the temperature of the heads over time at different input pressures. There will be a balance point where the load is going down initially, but then rises as the total amount of air being compressed on each stroke leads to higher heat load because the total amount of air being compressed on each stroke is higher too. But you should be fine where you are now.

Thanks for the bump.

I’m still working on insurance, which will be the main limiting factor for this to happen. Table pricing will be in line with the Midwest show.

It's illegal to deny transferable warranty when there is one remaining. Contact your State Attorney General or Consumer Protection Office in such event, and file a suit in small claims if needed. Also follow up with the BBB (Better Business Bureau). Speaking of the BBB, the company currently taking over the US operations for FX has a terrible review rating with BBB currently.

i think a forum title should be Air Gun Shows . where the upcoming shows dates and address (web page) can be listed this would promote the shows and improve attendance .
Being able to make plans to go to a Show in advance would be very helpful and it would be free advertising for the shows promoter . I have met a few people at shows the were only an hour or two away but didn't know about the show until i posted i was going (which is why i usually post several times with updates )

OP, that is a very nice C600. I don't believe that serial number are an accurate means to to date a 600, but I could be wrong. There were three variations and the first & perhaps second had the "short stroke" safety slot and corresponding notch in the grips. The third variant, and perhaps second has the stop and the stop roller in the trigger group.
