No, a CO2 bottle gets filled on weight, not pressure like most gasbottles. A full CO2 bottle at roomtemp is about 2/3ths full of liquid.

Overfill a bottle, and it heats up after filling (filling a CO2 bottle is best done with a very cold recieving bottle, and a roomtemp donorbottle) , the pressure will rise very fast, untill the burst disk blows.
