Win Model 250, lever action 22, bolt assembly. Where do the two very small ball bearings (plungers) go in the bolt? I had my gun worked on several years ago and finally got around to firing it. It misfired alot. I disassembled the bolt and the two plungers were missing. I got replacement plungers (as well as fp, fp spring and hammer spring), but I'm not sure exactly where they go in the bolt. It seems they might go on either end of the fp spring (against the extractor on one side and the base of the fp on the other), but I'm not sure. Couldn't get help from Winchester, Winchester Owners Forum or NuLine. If anyone's been here, done this, help would be appreciated.

That is correct.

Still clicking, not in a good way.

Thanks. I knew i could count on this group. BUT, now I guess I have a different problem. I assembled the bolt this way (plunger at each end of fp spring) and took it out to test fire. Shot 14 consecutive rounds and functioned like it was new. I thought, awesome, aren't I clever. The next day I got my friend, so I'd have someone to brag to, and took it out to sight in. Click, click, click. It fired two out of about eight. Crap. So... I'm going to break it down and check out the fp, spring, etc to see if anything obvious. I'm sure I'll be back soon, asking for more free advice. BTW, this has been posted on winchesterowners forum for about a month, and as of yesterday still had NO replies. You guys rule.

Fairly common on this family of rifles, is the barrel coming loose. The barrel is held in the receiver by a nut, access is by removing the forearm and the rear sight.

To check for a loose barrel, open the action and see if there is a gap between the back end of the barrel and the receiver. There will be a seam, but if you see a gap then the nut needs tightened.

The front end of the bolt is long and tapered. Sometimes crud builds up on the barrel where the bolt fits and the bolt cannot close enough. It's kind of a pain to clean, but is another source of failure-to-fire.
