>>The 338 ARC was developed to
compete with the 300 Blackout
and 8.6 Blackout for mainly
suppressed subsonic use. It is
able to run the heavier .338
calibre bullets like the 8.6
Blackout so it has more energy
than the 300 Blackout, but is
still able to run in the AR-15
platform unlike the 8.6. It is
capable of supersonic loadings
as well, but keep in mind that
many of the .338" hunting type
bullets were designed for the
large magnum calibres and may
not perform properly on game
at the slower velocities. Many
companies are putting out
bullets designed to expand at
the subsonic velocities that
would work well in this
cartridge for hunting
applications.
