put 12 through the chrono and its saying average 536fps i was using 14.76 grain pellets (min527, max545, dv18, sv5)

I think i might have got the 11ft/lb from transposing the numbers in my excitement

So i looks like im down at 9 something ft/lbs

As it needs a better spring guide anyway i might as well do the tinbum tuning thing, also i now have a borrowed chrono so i can set it correctly rather than guessing really low.
