I used my mike (Micrometer), actually I used two to check each other to measure several pellets of each.
When shooting Clays I believe I can tell a difference between
real 7 1/2s and 8s.. Stan,what do you think?
Of course under about 35 yds it does not make much difference.
I also like Rios a lot, but will make sure I have "7 1/2s"
