I was wondering if anybody on here knows what to do about this. its a bolt gun with the tube feed and it is probably 20 some yrs old. my old man said it has always misfired a lot. he sent it off twice way back when to have it fixed but it still misfires. they told him to use federal ammo and it would not happen as often. i know about 6 yrs ago my buddy got a marlin bolt gun from walmart that was stainless and mag fed and every now and thin it would misfire. them 2 guns is why i have never purchased a marlin
