Re: tuning kit for my pro sport

I used a Tinbum drop in kit and it's taken the twang and cocking graunch noise away completely. Pellets fitting tight in the breech (anything over 5.52mm in mine) give a definite louder report.

Re: Prosport cocking lever

Also caused by main pin holding the lever to the bear trap mechanism block being slightly off centre in the bushings, as I found out when rebuilding mine after a respray.
