12g crossman Co2

[DJS]

The silver coloured crosman ones are usually a little more expensive at around 80p each this is because they contain silicone oil.

I still haven't seen any evidence of Crosman co2 cartridges containing any oil. Crosman don't claim that they do and recomend putting a drop of silicone oil on the odd cartridge. I've cut open a number of them and they have all been dry
