I was at the range one day and a guy came with his latest purchase of a 1891 Mauser Carbine in what he was told was 7mm Mauser. So he proceded to try and get the gun sighted in at 50yards, no luck. So he put a target at 25yards and the bullets were everywhere. I started to look at his cases and noticed that he was shooting 7mm Mauser cartridges in an 8mm Mauser gun. I took one of the cartridges and tried to compare the end of the barrel to the bullet and it was quite sloppy. But it did fire.
