222 Rimmed
Historical Notes:
The 222 Rimmed originated in Australia in the 1960's as a cartridge for single
shot rifles, particularly the small Martini action. The 224 R-C
Maxi, based
on the necked down 357 Maximum, practically duplicates the 222 Rimmed because
both have the same volumetric capacity as the 222
Remington. Cases are
manufactured in Australia and have been available through Jack C. Miller,
Shooters Supplies Pty., 302 Russell Street, Melbourne, Australia. Headstamp
is SUPER, 222.
General Comments:
This is a good cartridge and can duplicate anything the 222 Remington can
do and is useful for the same range of game. These cases tend to be a little
heavier than the 222
Remington, and while loading data for the 222 can be
used, it should be reduced by 1 grain when approaching maximum. American
shooters might be better served to go with the 224 R-C Maxi because the basic
357 Maximum brass is easier to to come by than the Australian rimmed case
and the performance of the two is virtually identical. Brass can be made
from RWS 5.6x50Rmm cases, but they are relatively expensive.
