No, although I prefer to use 8d on the walls and 10d on the roof
sheathing. What concerns me
most is that whether they are using common nails or galvanized box
nails, the only two types
listed in IBC Table 2306.4.4 for shear walls. Who knows what they use
in nail guns.

We had a project several years ago where a church addition was being
framed by volunteers who were overseen by a supposedly experienced
foreman. We called out 8d common at various spacings and I saw a wide
variety of nails (roofing, 8d, 6d sinkers, etc.) being used. They were
however nailed at the exact spacing called out on the plans. Once this
was straightened out, they used the correct nails at the correct spacing.
