I had set my pellet speed on a brand new Lelya .25 with JSB Kings at 270 m/sec ( 890 f/sec). half a year ego( regulator set to 140 bar) Today , I guess approx 3000 pellets onward I put the same pellets over the Chrono and measured 255 m /sec ( 840 f/sec) .
deviation in both cases was small ( approx 4 m/sec) and never shot under reg setting . Both speeds measured with approx. 20 pellets in a row).
anyone an idea how it can happen that pellet speed decreases in such way ?
P.s the only thing I did That could be a cause but I dont know how is that I have been replacing the handle sprngs . It was kind of difficult to get the airtube back on the stock so Imhad to fiddle with that one quit a bit to get it right again. Could during this process somethng have happened to the regulator setting or hammer spring ?
