Well, Eddies are not that bad actions exept that there were batches of them (not all) right down to hard. Many accidents were experienced that overloaded handloads and even the factory ammo over extended period of time did shatter the receivers and especialy bolt lugs. Optimum hardness of receiver is in the range of 40HRC and 45HRC for bolt. Many of them were in excess of 50HRC and even they would stand to couple of "blue pills", extended shooting would cause the micro cracks and then final catastrophic failure. Eddies are very serviceable actions but only after making sure that they are not to hard and if they are then new heat treading is in order to save them from garbage.
