Wind is a factor on anything at 100 yards if the wind is strong enough

with maybe the exception of extremely high BC bullets like 300 grain .338 and 900 grain .50 cal boat tails, which drift just under an 1'' @ 100 yards in a 90 degree 10mph crosswind, most bullets will suffer from some wind deflection at 100 yards

It's almost completely dependent on the bullet's ballistic coefficient. While 100 grain .243 grain bullets don't usually have bad B.C's, they don't quite hold up to the heavy for caliber 6.5mm 6.8mm and 7mm boat tails.

A 100 grain .243 VLD bullet should have just over an 1'' of wind drift in a 90 degree 10mph cross wind. If you're using a flat based bullet, or a bullet with a less aerodynamic shape, you will suffer from more wind drift.
