I bought this Remington Model 597 .22 Magnum, a semi-auto. At least once during a mag load, I will get a FTF or FTE. I was told that Remington had issued/selling updated magazines, in fact there were three different types, the newer ones supposed to solve the problem. I bought the newest version, but was still having problems. My son, in Army Eod/former paratrooper suggested I take the magazines apart, clean the insides and stretch the springs a little. That did not help either. a gunsmith suggested, I have the loading ramp polished. Have not tried that yet, but until that is done, anyone else experience this problem and arrive at a solution?
