>>The 8x57 IRS was born at the
same time as its rimless
brother 8x57 IS. The original
idea was to develop a similar
cartridge for the breech break
combination guns like double
rifles, drillings and
vierlings. The other
difference to 8x57 IS is the
lower maximum pressure level
which has been set for this
caliber to 330 MPa. Throughout
the decades, the 8x57 IRS has
earned its success and
reputation as a powerful wild
boar stopper in driven hunts.
>>Lapua cases are the best in
the world. The base, body and
neck of Lapua cases have been
designed to maintain exact
tolerances over multiple
reloading cycles. Advanced
metallurgical research and
manufacturing techniques
ensure that Lapua cases are
leaders in uniformity and
quality.
