I think the 7mm-08 fills the bill as the least hyped, but super successful cartridge. I know that I don’t remember much being said about it for it’s first 10 or 15 years. I think it started out as the darling of the silhouette crowd. It took me about 25 years to understand that I needed one. It does all that my 270 before it did, and has become one of my favorite cartridges. From what I can tell, it is continuing to grow in popularity and rightfully so.
