| Warning! Notes: This cartridge offers significant bullet weight versatility, ranging from 32 grains for pelt hunting to 44 grains for improved long-range shooting. The 19-223 Calhoon drives heavier (better ballistic coefficient) bullets than the 17 Remington at similar velocities. The 223 parent case is necked down to 19-caliber in one pass through a forming die and the case shape subsequently formed by fireforming. With a 30-degree shouder, the fireformed case attains the powder capacity of the 222 Remington Magnum and delivers velocities normally associated with the 220 Swift. The 19-223 Calhoon can be accommodated in firearms suitable for the 223 Remington-length cases. It works well with 26-inch barrels using a 1:13 twist. James Calhoon Mfg. offers rifles, barrel kits, loaded ammunition, reloading supplies, and components. Cooper Arms also chambers single-shot rifles for this cartridge.
