    I am looking for a list that cross referneces MM to Inches. Like what a .270 is in mm and so on for all bullets. I saw a list like this on the net one time, but I can't find it anymore?

    There are 25.4 mm in an inch, so .308 X 25.4 = 7.82 mm
    .243 X 25.4 = 6.17 mm
    .257 X 25.4 = 6.53mm
    .277 X 25.4 = 7.04mm
    .338 X 25.4 = 8.59mm

    If that helps any
