I have 2 BX triggers.  One on a TD that has been awesome from the first round.  

Another I put on a standard 10/22. That turned into the world's ugliest sleeper.  SOB shoots! Last year I got a suppressor and shot quite a few rounds thru rifle No2 without a issue.  

Yesterday I experienced some reset issues.  To get it to reset I would have to pull the bolt back as far as humanly possible.  Then it would be OK.  Then out of nowhere it would do it again.

And ideas?

take it out and inspect it, see if it works out of the gun and maybe swap the trigger packs with another .22, see if its the gun or the trigger.

Id probably start with a good cleaning. Rimfires are dirty any way, putting a can on it isn't going to help.
