I never understood why someone would take out a perfectly good rammer to put a twisting spring in. My Fenman is 30 years old and shot loads with never needing anything done. Heck, I sent it off five years ago for a service, just to be sure. It was returned with: "nothing needed doing".
They point rather well. There are better triggers out there, but the one they have is good enough.
Such of the fun is The Project. Well done, but more than I would take on.
I shoot RWS Superdomes .177 in mine and can hit small things out a good way.
