Accuracy was ok but never really good.

In the end I fit a somewhat reduced spring that gave it a more pleasant shotcycle, a fresh seal and fitted guides, and sold if off cheaply with clear info that it had been soft-tuned.
Pretty much my experience with my .177 57. Bought it from Germany back in 2019, it was running at 6ftlbs due to the German market mainspring. Re sprung it with a cut down 97 spring, big mistake, 13ftlbs and awful to shoot, after a chop and coil collapse, now running at 9ftlb. Still not as accurate as i'd like. I think the longish stroke and light weight go against it.
