haven't heard of one....
But there was a recall on the Model 600 series rifles at one time, for this same problem.
Also be aware that if the trigger mechanism is "gummy" (from crud, or thickened oil in the cold) that pulling the trigger with the safety ON could result in firing when the safety is taken OFF.
And, if some one has "adjusted" the trigger, it could be set with insufficient sear engagement to remain cocked, which could also result in it firing when the safety comes off.
Get thee to a qualified gunsmith and have the rifle checked, it may need to go back to Remington. DO NOT LOAD IT AGAIN! (I know you know this, but it needs saying).
Good Luck, and please keep us informed as to the final results.
