is there fix for the contender with a 14 inch 35 remington barrel. mine will not fire factory ammo reliebly ,some times it goes bang some times it wont. now if you reload once fired brass shot from the same barrel it goes bang every time . it is hit and miss on virgin brass reloads also.a friend told me this is common with the 35 remington and the contender. he claims the sholder on the 35 remington allows the shell to move foward in the conteder .I must admit the sholer looks sharper on once fired brass .
