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. Is there a way to bring modern performance to the low pressure cartridges through advanced projectile design and manufacturing? At Lehigh, the world's most innovative projectile and ammunition manufacturer, the answer is a bold YES.
