The .338 WinMag and .458 WinMag share a common case. When the .338 is necked up to .416 or .458 is necked down to .417 it is the .416 Taylor.

Is there a .375 cartridge based on the common case?

This is sometimes referred to as the .375 Taylor.

here's some load data for the .375 Taylor.....also called the .375-338 and the .375 Scoville....it's a powerful SOB!!!!!
