It can and has happened. The minimal amount of these that happened were factory set rifles. And as I recall most was when the safety was put on and taken off! Of Course, the liberal news stations tried to make it into shooters thinking it was a regular occurrence which it is not.. In an attempt to slow gun purchases no doubt discredit the Remington Gun Company! It can happen if adjustments have been made incorrectly by the factory or an owner or back yard gunsmith! If you know what I mean? Improper adjustments can make this happen very easily. But I do not think it is of much concern. If one gets a new 700 series rifle they should check to see if they can get this issue to occur with their new rifle when the get it home. I have several Remington Bolt guns with factory set triggers and also with easily adjustable triggers. I have only had it happen to me while adjusting triggers. Simple fix! Proper Adjustment!
But should not be done by a novice or someone who is not familiar with the correct procedures and trigger adjustments. That is why Remington advises if anyone has any trigger issues to send it back to the Factory or one of their Service Centers. An incorrectly adjusted trigger is simply a major liability!
