I bought some .243 win the other day and didn't notice the word "Express" until I got them home. It sure gave me pause!! All I could think about was the 7mm Express and how easy it would be to confuse some of these cartridges. I finally took out the caliper and measured; its 243 win. 7mm mauser is not the 7mm express; one word out of place and a guy will not be having a good day when pulling the trigger.
