I prefer the bolts to lock closed when safety is engaged on my hunting rifles. All my 700s are post 1982, but I have installed early safetys in most of them to convert to locking bolt.
The exception was my newest 700, made in 1997, that no longer had the bolt factory machined for the bolt lock safety. I solved this problem with careful use of my dremel tool, it turned out great, and has less bolt wiggle on safe than the factory machined bolts.
