Lehigh .308 Cal Xtreme Cavitator 85Gr 50Ct

There are many excellent older cartridges with performance constrained by the metallurgy available for the firearms at the time they were designed. Some are so good, as in the 45-70 Government, they have been updated for modern pressures and re-released as modern cartridges, others, like the 32 ACP will probably remain with low operating pressures, due to the number of guns in existence.
