James you dont think the 7mm-08 is popular. I think there are more 7mm calibers in rifles then almost any other if you add them all up. Excluding wildcats if you take a 277 bullet which is one of the most popular calibers there are there arent that many cartriges for it. 270Win, Wsm, Wby thats about it other then the wildcats.

It would take half a page to list all the calibers with a 7mm bullet unless your just talking stuff that has mm after it and if so never mind my post.

I dont think the 6mm ever got the attention it should havecompared to the 243 but I think the 7mm caliber is one of the most popular calibers we have next to .308 if not the same.
