S510 ultimate sporter

Fri Jan 08, 2021 7:19 am

Well its been a while since I've graced these pages. What with children and other things going on. Well I hope everyone's well. My question is I've recently acquired an s510 ultimate sporter , the unregulated version, in .177 . After a chrono testing session with all manner of pellets yesterday , I am getting an average of 10.1 with jsb exacts/aa fields and 10.3 with jsb heavies. Which it's a little low for my taste. Also there is some variations between shots half way through the sweet spot. Anyone found these low on power? Is there anyone on here who works on them(I don't touch pcps! !) And who would also fit a reg to it for me? Happy new year to all. Les

You dont have your location set so he may not be "local" to you. I had a S510 US reg'd by Phil at The Rat Works https://www.theratworks.co.uk/
