Off the top of my head, the most accurate guns have been:
Avenger Wood
Steyr LG110 Black
RAW Chassis Gun
Cricket 2
Daystate Pulsar
but also:
....Impact M3
...and the RTI Preist
....and the SK-19 in .25
My shooting ability has got alot more "confident" as of the last year or so. ...so some of my early reviews, such as the Red Wolf and Tiapan, I'm not sure if my shooting was as good as I could do now.
