I just purchased a CO2 pump and 3 16g cartridges. Replacement cartridges seem kind of spendy at the bike shop. My question is has anyonone used 12g C02 for BB guns? It seems to me that the cartridges should contain the same presure (much higher than 100 psi) so what the 12g lacks in volume can be made up by using another cartridge. The cartridges for BB guns are much less expensive.
Thanks for the advice.
