I've been using Jim Legg's recommended engine assembly lube for a couple years now. This was made by Coastal, as I recall. Excellent results. My Browning XS has seen nothing but this product and is as tight as when new 7,500 targets ago.

Don't overthink this. What's important is a film of lube that stays where it's put.
