I find it hard to believe that the accutrigger spring would slip off, unless someone was modifying things such as cutting coils, or doing something else. I have had several accu-trigger guns and ran them at or under the 1 lbs area, and never had a spring slip. I have a target accutrigger that was tweaked and breaks at a consistent 4oz, this rifle has fired hundreds of rounds in Benchrest competition, and never failed. The most common problem with the accutriggers is associated with the weight of the clunky heavy factory bolt handles, and the trigger will slip and cause the trigger to lock up against the safety leaver. Savage tried to band aid fix this problem by placing a rubber bugger under the bolt handle in latter models.
