22 BR Remington Cartridge
Historical Notes:
The 22 BR Remington is based on the 308 x 1-1/2 inch Barnes case necked down to
22 caliber and lengthened by 0.020 inch with the shoulder angle increased to 30
degrees. It is difficult to determine who originated the 22 version of the
necked down 308 x 1-1/2 inch because there are a number of them dating back to
about 1963. J. Stekl is credited with having developed the Remington rendition.
In any event, Remington standardized the dimensions in 1978 as their 22 BR. It
is one of the series of BR cartridges including the 6mm and 7mm, all based on
the same case. The 22 BR is a factory wildcat because loaded ammunition is not
available. Brass must be made from special Remington or necked BR cases which
have a small rifle primer pocket, or from full size Remington 6mm or 7mm BR
cases. The 22 BR has won many honors in benchrest competition and has great
accuracy potential.
General Comments:
The 22 BR is similar to the 22
PPC but has a case of larger base diameter and slightly greater powder
capacity with the same case length. There isn't anything one can do that the
other can't duplicate. Both can push a 55 grain bullet at over 3000 feet per
second and duplicate the performance of the 223
Remington. Both are extremely accurate and make excellent varmint cartridges
as well as benchrest competitors.
