" (700 trigger) now breaks at 1# like glass, no creep, no overtravel. "
You've made a mistake that invites great hazard. That's target trigger quality and the 700's trigger was designed and produced to be an excellant hunting trigger. Mike Walker is a friend of mine, he's the man who designed it and he assured me that his trigger MUST have something like a 3# pull plus have a bit of creep AND overtravel to insure that the internal floating 'trigger connector' will perform properly. (AND the internal mechanism has to be kept clean, free of gummy dried oil or the connector cannot work properly. I give mine a spritz of carborator cleaner each year and follow with a few drops of Automatic Transmission Fluid; great gun lube, it's slow drying and non-gumming.)
Now that you've tried to 'bump it off', try it again (empty chamber) but this time have the safety ON and pull the trigger before and during the bumping; the sear is blocked so it can't fire then but it's quite possible the pin will fall when you release the safety, even without touching the trigger because the internals are too tightly/lightly connected to allow the connector to reset after pulling the trigger with the safety on. People have been killed that way and the shooters blame the trigger for their foul-up.
Either get an after market 700 trigger that's made for target work or readjust your's to not less than a 3# pull and with a slightly detectable creep and a little overtravel.
