i've got an old 700 that will do this if the trigger is set too low.
One of the downfalls of the Walker trigger is that it is immanently adjustable. I've bought a few M700's--including here on the 'fire--where the sear engagement was dangerously small...
A couple more older M700's probably never had their stocks removed and the underside of the rifle cleaned. The trigger housings were filthy, and PACKED with crud.
Those two situations probably account for 99% of the alleged "accidental discharges".
But few want to hear that.........
