As most know the Air Arms S510 is unregulated. I enjoy bench shooting in my backyard and was tired of poi changes. So I decided to try tethering my 4500 psi bottle. I bought a Ninja High pressure Fill Station 6000psi regulator "used" on ebay. I had to replace one gauge. These are some pictures of my setup. I was shooting 50 yards. The Chrono is a Caldwell. Tried to graph it (very unprofessionally I might add) If anyone has a better program to show curves.....Please let me know. The poi has defiantly improved. These were 50 shots. I am using .177 JSB 8.44. The regulator is set to 160 bar. I also have the power adjuster set to half way. Still playing with it but here are some initial results.
