Title: Tuner/airgunsmith in Tulsa, OK
Post by: packard8 on July 23, 2017, 10:59:41 AM
A friend of a friend has an older RWS Diana model 40 in .177 that needs some attention. He brought it over to my place and I ran a few shots on the chrony with CPM 10.5's and only got 330-350 FPS. The cocking effort is light, so I suspect a broken spring. I don't have a spring compressor, so I can't really help. If anyone in the Tulsa area does repairs or tuning please let me know either by reply here or PM.

Thanks!

John
