Mine was at 2 lbs , didn't have time to figure out why, just cleaned/lubed with lighter fluid and reinstalled, no joy. So I got a timney as that's what was available on short notice at the time and got the rifle up and running again for the match and haven't revisited it since. It was just a learning experience for me in that its just one more thing on the checklist of things to verify before a match.
Probably shouldn't have to worry about it, but its a mechanical device no matter how you slice it, it can fail, and its the reason we have the safety rules we do at matches, shit happens.
EDIT: just figured out you were talking about Mike's
