Various posters have explained that the U shaped pin set is not only common to the BL and 57 series, but presently used on the 680 series guns being sold by the boxcar load today. The replaceable shoulder system of the 682 Model is not used on lesser priced models and they seem to survive just fine. I am not entirely sure that the locking lug holes are the wear point. I have tens of thousands of rounds through one barrel set of a five barrel set 682, few rounds through the other four sets. When the pin set was replaced when the gun was about 15 years old (because of well worn lever position), the unused barrel sets showed a lever position similar to the well used set. I think the pins were wearing as well as the holes, maybe more. With either the old or new pin set, the lever position was similar on all barrel sets. Mr. Cole's observation that the trunnions don't seem to wear parellels my experience with my high mileage 682. It opens and closes like it is still breaking in. Precise fit of the side walls of 680 series actions as well as careful cleaning prevents wear on the trunnions. The tight fit of the shoulders helps also, I assume, but only one of my five barrel sets was fitted at the factory so the assumption would be that some of my shoulders are not as well fitted as others. I think the shoulders are a nice touch, but not neccesary to the longevity of the gun.
