Hi guysJust a thought re my Crown.
My scuba tank has gauge checked, within 2 or 3 bar accurate.
Fill gun reservoir gauge agrees with scuba gauge.
If Reg below setting, mine reads 130 bar max. So let reservoir and reg fall below 130 say 120. Fill gun to 130 , scuba tank reads 130 and Reg gauge 130. Must mean they are all within scuba tank variation eg 2 to 3 bar. 
Am I missing something here?safe shooting
 
Well, just the other day I tested both the gauges on my Crown for accuracy comparing them to my Edgun EDMU digital gauge. Here's what I found. I tested the gauges twice and the results where nearly identical. Both FX gauges are nearly dead on or read slightly more than the EDMU's pressure until 150 BAR. At which point the FX gauges get progressively inaccurate, reading less pressure than the EDMU reads, as the pressure increases up to 250 BAR.

Thanks for that. 
Good info 
So assuming most Fx gauges within those margins as above I am content.
For me reg is as good as accurate then , impossible to read exact amount anyway, the line marks probably take up 1 bar plus. My gun will never have reg gauge over 150 so satiisfied there.
Re bottle gauge will check between scuba and gun more carefully. Normally wouldn't fill above 230 bar which + 10 is still ok. As previously stated scuba bottle at 250 bar is within 2/3 . 

At least with quality gauge on scuba know that my checking system is ok.
Will be watching out for reg creep like a hawk!

safe shooting
