The .35 Newton was one of a family of high-velocity cartridges designed by Charles Newton in the 1910s, predating modern magnum rifles by decades. Operating well above the pressures considered safe by contemporaries, Newton designed rifle actions capable of handling his cartridges. The .35 Newton offered performance approaching modern .35-caliber magnums nearly 50 years before Weatherby or Norma achieved similar results.

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…
