You need to be careful with this ammo. I contacted the manufacturer and they load with .308" bullets. The original bullet diameter of a 7.5mmx55mm Swiss is actually .305 inches! So smaller by .003 inches. If you have a tight bore like my Swiss K-31, DO NOT BUY THIS. If you have slugged your barrel and it is a little worn in Swiss 1911 or K-31, then this will be a great round for your rifle. Again, be careful with what you buy and check your barrel.
