timetofly-what ammo did it seem to like best?
What fed the best was Federal 40 grain lead round nose 1080 fps. This shot well in my bolt action rifles, but it's not match grade ammo. At 50 yards the Federal would be a 2" group where SKS would be a 3/4" group in a rifle. If I remember correctly CCI standard velocity worked well also. I've accumulated several different brands of 22 ammo and they all fed and fired perfectly after the first 300 rounds. I think that the Kadet just needed to break in.
Good luck with the Kadet and happy shooting.
