.375 Holland & Holland Magnum vs .454 Casull

.375 Holland & Holland Magnum

.454 Casull

Developed by Dick Casull, Duane Marsh, and Jack Fullmer in 1958, 454 Casull Ammo is a powerful wildcat firearm cartridge. The design of this ammo is based on the .45 Colt case, so both .45 Schofield and .45 Colt cartridges can fit well in 454 Casull’s chamber. Because of the high chamber pressure of over 60,000 CUP, this cartridge uses a small rifle primer instead of pistol primer. 454 Casull Ammo comes in a .45 colt case that is about 0.10 inches in length. Bullet weight is around 240 to 300 grains and delivers a muzzle velocity of 1900 feet per second. These rounds can be loaded to a maximum of 65,000 psi pressure and the pressure when fired will be over 60,000 CUP. 454 Casull Specification: Cartridge case: .45 Colt Case type: Rimmed straight Bullet diameter: 11.5 mm (.452 in) Neck diameter: 12.2 mm (480 in) Base diameter: 12.2 mm (.480 in) Rim diameter: 13.0 mm (.512 in) Rim thickness: 1.4 mm (.057 in) Case length: 35.1 mm (1.383 in) Overall length: 45 mm (1.77 in) Case capacity: 2.95 cm3 Primer type: Boxer Small rifle Maximum pressure (SAAMI): 65,000 psi (450 MPa) The 454 Casull is a hard-hitting handgun cartridge perfect for hunting dangerous animals.
