All steel tanks are 3000psi to my knowledge. Some carbon fiber tanks can hold up to 4500psi, which means over 50% more shots per cubic inch.
I think the biggest steel tanks are 62ci or something like that, whereas carbon fiber tanks can be over 100ci.
It is my understanding though that some places don't fill to above 3000psi so you may want to consider that. Around here, they fill to around 3500-4000psi.
