take a 90 grain vld bullet in 223 versus a 185 grain vld bullet with roughly the same velocity and bc out on a windy day and you will find out how wrong this theory is.bullet weight does make a difference with wind drift.This has been tried many times by alot of the top shooters in the world and the results do not change.Sometimes the math is trumped by good old fashioned experience.
