Most of the guns that had this problem were the model 600 and not so much the 700. The safety has to be OFF on the model 600 for the bolt to be opened and the round to be removed from the chamber. The model 700 you can open the bolt with the safety on and thus eliminating almost any chance of an accidental discharge. Someone thought it would be a good idea on the 600 that if the safety was on then the bolt wouldn't open,so if you were walking through to woods with the safety on and a tree branch hit the bolt handle the bolt would not open accidentally.I personally have shot tens of thousands of rounds out of a M40A1 sniper .308 and never had even one malfunction(and yes I know some of the parts inside the weapon were changed out by the armory but all of the rem short action safety parts remained stock),But I have also seen the same gun(not mine) have a misfire and when the bolt was opened the gun went off. Was it a fluke or a delayed primer? The world will never know. The model 700 is one of the best rifles that I have ever had the privilege to shoot,and I have shot many weapons in my day. I am not a spokesman for Remington or affiliated in any way, just giving my two cents on one of the finest weapons there is out there.
Don't Try To Run From The Sniper You Will Only Die Tired.
