CO2 and ISSF rules, banned from the range?

I have a bit of a dilemma starting 10 meter precision shooting. I have a not so cheap CO2 Walther CP2, a CPM1 and a Feinwerkbau C10 pistol offers in the second hand market but the ISSF rules say any cilinder +10 years old is not valid.

That excludes all those guns from competition except if they have a kit to use 12g disposable bottles, no cilinder no problem right?

It's posible to use this arrangement and keep using those old great guns in a ISSF competition? They will kick me for contributing to global warming? Do i need a SSP or a PCP?
 
Appears CO2 nonissue with ISSF.
