6 mm came in 7th out of 10?

I have a 6 mm 700 rem. in my collection, with a well placed shot it is a fine round for white tail size game I use it often due to range and the light recoil. But in a list of 10 most favorite, I think in Field and Stream in came in 7 that surprised the poll and myself. I seldom find the bullets in many stores. Is it that popular in this group?
