The hollow bolts were made about the last seven months of 1971. Manufacturers do not throw away good parts, so I understand there was a period of time when (in long actions) flat bolts, round bolts and hollow bolts were all being boxed up. All the while the short actions were all flat bolts.
The idea the ST (Sights and Tapped for scope blocks) came first is wrong. They came a little later.These are sometimes called RTs, I guess for round top, but that was never a factory designation. There was also a PL which stood for Plain. These were non-sighted rifles tapped for scope blocks and were basically STs without the sights. These were only available to distributors who sold at a certain level.
As for the vertical split rings, that is probably the second most rare item to ever be shipped on a Model 77 from the factory. Much more rare than those on the early No.1s.
