I had one in the seventies, and my experience echos airdale's. I grew up shooting my Dad's Win. 63, so I thought I needed a high quality 22 semiauto. I figured if it had Weatherby's name it had to be good. There were shots I knew I could make with the Win. 63 that I couldn't make with the Weatherby. I sold it.
Today I shoot a Thompson Center 22 Classic, and I like it a lot. They can be had in the $279 range, new gun. It's the best deal out there on a top quality semiauto, IMHO.
If you are not definite on a semiauto, the CZ 452 bolt action guys seem happy with their guns, in the $200 - 300 range.
