Well I went to chrono my setup that is alot like yours this morning. Went from 295 to 245 after a 30 shot burst. Bottle started getting cold but generally shot to shot consistency ranges in the 15 fps for slower fire rate. Have a anti siphon tube already but I'll have to install a palmers reg to have to get regular consistency. Plus co2 doesn't work that well in cold weather but it's only 60 degrees here?
