History
Charles Newton was a visionary cartridge designer who understood the relationship between case capacity, pressure, and velocity decades before it became mainstream. His Newton rifle company produced several calibers — .22, .256, .30, .35 — all with unusually high velocity for the era. World War I disrupted his business, and repeated corporate failures left Newton in financial ruin. The cartridges died with his companies, though they are admired by ballisticians as historically significant designs.
