LAPUA BRASS 8X57 IRS 100PK - SKU: 4PH8031

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.
