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.
