I use a Dreamline Lite Bottle version (580cc) and @ 30Ftp I get 7 mags and somwhere on number 8 it falls of the regulator (set on 120 bar). This is a shot count of about 130 shots. I'm waiting on delivery of a power plenum and the Huma High flow probe to be delivered next week. The goal is to reduce the regulater pressure and get an higher shot count on the same speed of about 920 feet per second. Then I'll do some testing on settings to get the best results. (the bigger bottle costed 40,0 Euro extra).
