surely the seals will stand up t0 300 bar i thought it was limited to 200 bar for the air cylinder

HW100 in any format is regulated . if the cylinder is been passed for 300 bar you should be ok .
Speak to one of the turners ie Carl airtech or Phil ratworks

[threelander]

its Carl talking to and the cylinder will be proofed well over 300 bar

You could get away with it and never have an issue but you are using the gun outside it intended working pressure , don’t forget divebottles are tested to above300bar add a bit of moisture and they will go banglet alone a rifle that could have worn seals.
Surely if you want an extra shot count it’s better to buy a HW100 or a aftermarket cylinder for the “K”
