That is terrible...I had that happen a few times at the range...I was using a friends 06 ..Come to find out it was the firing pin spring....too weak. One reason I don't buy used guns...That is a heart breaker though...It's hard enough to get a shot at a deer at the Green Swamp let alone stuff like that happening..I searched this problem on the net...There has been many Remington mis fires..I shoot winchester with my 270 and 30-30 but shoot Remington with my buckshot and turkey loads..now I'm a little uneasy..I plan to switch to WInchester with every thing...That concerns me..There have been many reporting Remington mis fires...not taking any chances..
