Also can I shoot IRS ammo out of a bolt actionYes JS and IS are the same.
It was designated by the Germans as IS, I for infantry and s for spitzgesschol (spitzer), but, the way they wrote the I looked like a J to the English and Americans.
The bullet size is .323 for the "modern" 8x57 IS compared to .318 for the original 7.92x57 M/88 cartridge.
Ok thank you so much!IRS/JRS ammo is rimmed and uses a .323 bullet. I believed that was designed for break-action rifles and cannot be used in a Kar98k.
