I recently received this request for size information on glass bead.
It is very clear what is the nominal size of glass bead if one peens per AMS 2430 with AMS 2431/6 media.

I could not find what is the nominal size of glass bead with MIL-PRF-9954 media.I am just looking at the size for glass bead peening of threads using MIL-PRF-9954. The diameter should not exceed 1/2 of the radius with some exceptions.

Basically the question is what is the nominal size of MIL-PRF-9954 Size xx, for example size 10.
