8x57 IRS - The wild boar stopper in driven hunts

The 8x57 IRS cartridge 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 the 8x57 IS round is the lower maximum pressure level which has been set for this caliber to 330 MPa. Throughout the years, Lapua’s 8x57 IRS ammunition has earned its success and reputation as a powerful wild boar stopper in driven hunts.

The 8x57 IRS cartridge comes factory loaded with the 11.7 g / 180 gr Naturalis® bullet. Read more about the Naturalis bullet here. See product chart below for cartridge trajectory and velocity data.
