Tau CO2 question

okay…i need a cheapish rifle that’s innately accurate and fun/cheap to shoot. and still leaves a very little bit of custom room. this will be my “hey! welcome back to the states” gun…my condor will be my “welcome back to the states, long range shooting, the states, hunting nutria…” 😈 but i digress. im going to get the Tau/ CZ/ ALFA PROJ target rifle. its CO2, much like the Tau 200, and it’s based off of the Alfa pistol. in fact it pretty much is the pistol, just longer with some small changes here and there. anyhoo- here’s my question. since it runs on CO2, it should be easy to run it remote w/CO2. (brings me back to my paintball days.) but now that ive been so deep into PCP’s and also N2 for paintball, ive forgotten all about CO2. if this rifle’s supposed to run off of 12 gram carts (can be bulked), what psi should i run the CO2? im going to run a palmer’s regulator, to keep the liquid down, so i can shoot it in the winter, and shoot it slow, but those regs range from 200 all the way up to 8-900 psi. i dont know what to get. thoughts??
