Situation : have passed my ptw to chrony couple weeks ago and it whas around 400fps.. Havent touch my tw since... Received new bb this week an wanted to adjust the hopup before the new season... And the bb were falling 50' in front of me... Took my chrony with .20 and i was at 100fps and very inconsistent. Any idea ? Regrease cylinder to make sure everything is sealed in there ? ( velocity cylinder with less than a 1000 round through it )
