I agree with Padom above. Go for at least the special.
I like the special as I don’t really shoot much below 1lb, but it seems to be the new craze to shoot in the 8-10oz range. If that’s your choice, Diamond all the way. Best trigger I’ve ever owned
I can't tell you if the issue is your action or trigger, but I have the TL3 with a Trigger Tech Diamond and i've never had a single light primer strike
At some point, all things manufactured by humans can, and will, go down. But, Like Estes said, I'd like to know what happened so I can hopefully avoid the same thing at a match.
I had the exact same issue, TL3 and Calvin Elite. I mailed my bolt back to Bighorn too, still had issues after I got it back. Switched to TT Special, running like a champ now.
Ditch the timney and buy a TT like everyone else has said.
