Hi, everybody. I'm a new member from NW IL and I came to this site because I have a 93 .22WMR and It is having the same misfiring problems in this thread- it started off OK but as time goes on it misfires more and more no matter what ammo I use. Otherwise it's a great rifle, last time at the range my best group at 200 yds. was 7/8". I'll try cleaning and lubing the bolt and see if that helps.
