22 Waldog
Historical Notes:
The 22 Waldog was originated by Dan Dowling of Accuracy Gunsmithing in Arvada,
Colorado in 1980. He named it after a friend, Waldo G. Woodside, thus the Waldog
or Waldo-G. The cartridge is made by running 220 Russian cases through a
shortened 25/250 die and trimming the case to a length of 1.375 inches. It is,
in effect, a shortened 22
PPC case. The idea was to create a more efficient case than the 22
PPC by reducing the volumetric capacity to approximately that of the 222
Remington. The cartridge has been used, thus far, exclusively in heavy
benchrest rifles. Several 100 yard benchrest world records have been broken by
22 Waldog caliber rifles.
General Comments:
The 22 Waldog is another effort to develop a super cartridge. The current trend
is toward smaller, more efficient cases, and the Waldog has proven to be a very
accurate cartridge. The best accuracy has been obtained with 52 grain match
bullets and 24 grains of H-322 powder, but any powder that works well in the 222
Remington should give comparative results in the Waldog. Although not as
widely used as the 22
PPC, the Waldog has found a significant following among benchrest shooters.
It is similar to the 308x1.5 inch necked down to 22 caliber, also known as the 22 BR
Remington, as the two have similar case capacities. However, the
22 BR Remington case length is about .120 inches longer than the Waldog. Commercial
availability of 22 BR Remington brass will probably give the edge to the
Remington cartridge in the future.
