I have a 30+yr old .177cal air rifle that still shoots fine but I am sure it's not at top performance/velocity. It must have 50K - 100k pellets through it. I had the family shooting clay targets at 50yrd with it yesterday and tonight. The first night just holding over but tonight I sighted it in. I was able to hold the group to an inch or so sighting in on a 3" black circle with my 4x Banner scope. Everyone had a lot more breaks tonight as a result. The gun is still very accurate but I can't resist thinking that sometime it may blow a seal or break a spring. The rebuild kit is about $75 but I understand it's not an easy job. I got a quote today to send it out for repair would be about $225 or so.(Parts plus 3hrs labor at $45hr. I know for the same kind of money I can get something new. I also know if I wait too long I may not be able to get the parts for mine. So do I send it out for rebuild, buy the kit and hold it until I need it, try to do it myself or retire it and get something new? If I get a new one it would be 22 or 25 cal 1,000fps. I also have a old 22cal RWS Diana that isn't dear to my heart like my Webley.
