The few triggers that actually had a problem were about 30 years ago... a few got out of the factory with safeties that did not disengage the cocking piece from the sear... so when the trigger was pulled with the safety on, the sear was actually released but the cocking piece was held back by the safety, then when the safety was released, the firing pin was released and if loaded the rifle would fire.
The vast majority of "700 trigger problems" are directly related to incorrectly adjusted triggers after they left the factory or due to poor maintenance.
A real simple test - do it with an empty chamber... try and dry fire your rifle with the safety on, off, on, off... and slam the bolt closed and try and make it dry fire. This is something that should be done before every hunting season every year with every make of firearm you own.
