I have had a 700 BDL in 270 Win.for 40 years and have never had it go off without the trigger being pulled.
That said if someone has monkeyed with it then all bets are off.
Same thing with the rifle never having been cleaned other than to have the barrel swabbed and wiped down with a rag.
If used the way they were meant to be used and cleaned regularly,one should outlast the owner.
