Bought a new S&W M63 .22LR last night. Looked great but wasn't cheap. Get home and cleaned it up good and oiled it up. Can't get it to shot 8 straight rounds without jamming. Looks like the cylinder timing is off on a couple spots. I tried 4 differ LR ammo by differ manufactures but still no luck. I cleaned it several differ times but with no avail. I shot it again today. Loaded up 8 rounds, 27 differ times with several brands of bullets. Shot up, shot down and straight ahead. Out of 27 loadings I got only 5 loads that shot all 8 rounds without jamming. After close examination this gun is a bad example of a quality gun. The barrel throat looks like it has been threaded for a pipe connection with a couple threads across the lands themselves. I called the S&W tech and was told that was normal for barrel to be like that. Go figure!!! I'm sending the gun back to them. I guess I will see how good their service is. If not I guess I'll have a 700 fish weight.
