The .375 Whelen cartridge (A.K.A. 375-06) was developed in 1951 by L.R. "Bob" Wallack and named in honor of Colonel Townsend Whelen.[1] It is a .30-06 Springfield case necked up to .375.[1] While the .375 Whelen retains the .30-06's shoulder angle of 17° 30′, an improved version was introduced with a 40° angle, providing more case capacity as well as better headspacing.[1] The .375 Whelen Improved is favored by most.
