Lapua Naturalis 8x57mm IRS Mauser (8mm Rimmed Mauser) 180 Gr. Round Nose- Lead Free- Box of 20

Lapua has become very well known for their precision, consistency, and accuracy. Legendary, high quality components are used to produce this hunting ammunition to be used on all different types of game. Naturalis hunting ammunition utilizes copper bullets that retain up to 100% of their original weight for deep penetration, yet expand immediately upon impact due to a special valve at the tip. The result is dramatic shock effects on game. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

The 8×57 IRS cartridge was born at the same time as its rimless brother 8×57 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 8 x 57 IS round is the lower maximum pressure level which has been set for this caliber to 330 MPa. Throughout the years, Lapua’s 8×57 IRS ammunition has earned its success and reputation as a powerful wild boar stopper in driven hunts.
