7.7 x 58mm Japanese
The 7.7 x 58mm Japanese enjoyed mild popularity
among American hunters after World War II, when surplus military rifles were
imported to the U.S. The cartridge was adopted by the Japanese military in
1939 in the Model99 Arisaka rifle as a replacement for the older 6.5mm cartridge
but both remained in service during World War II. Norma ammunition loaded
with soft nose bullets is presently available
Some handloaders form 7.7 cases from
.30-06 cases,
but since the latter has a slightly smaller base diameter the best bet is
to buy Norma ammunition and reload those
cases. Ballistically, the 7.7 falls between the
.300 Savage and
.308 Winchester.
Bullets of .311" diameter (same as the
.303 British)
are available from Hornady,
Sierra, and Speer. A 150 grain
spitzer pushed to 2500 fps with
H414,
H335, or H4895
is a good choice for deer size game at close to medium ranges.
