.375 Weatherby Magnum
The Weatherby Collection
The 375 Weatherby Magnum was introduced in 1944 as an improved version of the famous .375 H&H
cartridge, blown out to a straighter case to increased powder capacity to produce 200 feet per second
more in velocity then the 375 H&H.
It was dropped from the line after the introduction of the .378 in 1953, and was obsolete and a high
priced collectible for many years until it was reintroduced in late 2005.
A 220 to to 300 grain projectile traveling  at 2,650 to 3,100 Feet per second to produce up to 5,350 foot
pounds of energy per square inch.
