.30 Newton: More info. The .30 Newton necked up to .358
caliber is very close to the .358 Norma Magnum in performance. You can achieve 3,000 fps with a 250 gr. bullet. If necked up to .375, its reported it will handily
beat the .375 H&H performance (its been done).
The .30 Newton was a favorite with Western Hunters due to
its long range capability, high velocity & power.
The late Fred Barnes (founder of Barnes Bullets) used one,
and it was highly praised by the late Phil Sharpe, a respected authority. Best Regards, Tom
