Just picked up a .177 Sub Compact Katran. I love the looks and feel of it. I filled it up and zeroed it in. Seems fairly accurate, but seems to be using up too much air like OP, and quickly. One magazine lowered the tank from 300 bar to 140. Pretty loud as well (tested w/Tanto). 750 fps w/CPHPs out of the box. Looks like I'll need to tear into it. I need to change the lever over to the left side anyways. This thread should help me, thanks for your effort @weevil , I can't seem to get the video in post 6 to work...it has left the youtuberverse. Would love to find some good disassembly and tuning vids.
